Investigating the Effects of Surface Area on the Rate of Reaction Essay Example for Free

Investigating the Effects of Surface Area on the Rate of Reaction Essay Aim: To study the effects of changing the surface area on the rate of a chemical reaction Hypothesis: This hypothesis is based on the Collision Theory, where in order to react, the two particles involved must: 1. Collide with each other 2. The collision must be energetic enough to overcome the activation energy of the reaction 3. The collision must bring the reactive parts of the molecule into contact the correct way – they must collide with appropriate geometry (the reactive parts) Considering that the surface area of a particle is a factor that mainly affects the collision rate of particles, it would be safe to assume that as the surface area increases, the reaction rate increases. The graph should turn out to be something like this: 1. the reaction is the fastest at the start 2. The reaction is slowing down here 3. No more product is formed Amount of product Time Variables: Variable Factor What is manipulated Dependent Time The time it takes for the reaction to complete depends on the surface area of the compounds being used, because it determines the rate in which the reaction will occur. Independent Volume of the gas collected (H2, CO2) The amount of gas collected for each experiment will depend on the Controlled 1. Mass of Calcium Carbonate (both marble chips and powdered form) 2. Mass of Magnesium (both ribbon and powder) 3. Volume of Hydrochloric Acid 4. Apparatus Used 1. The masses of the substances utilized will remain constantly fixed during the experiment 2. 50 cm3 of HCl will be used for every trial – 550 cm3 in total 3. The apparatus used will remain the same throughout the whole experiment Chemical Reactions: Mg + 2HCl → MgCl2 + H2 1. Magnesium ribbon 2. Hydrogen Gas will be the gas collected 1. 3 Trials will take place 1. Mass of Magnesium ribbon in: 1. Trial 1: 0.064 grams 2. Trial 2: 0.063 grams 3. Trial 3: 0.065 grams CaCO3 + 2HCl → CaCl2 + H2O + CO2 1. Marble Chips 2. Carbon Dioxide will be the gas collected 1. 2 Trials will take place 1. Mass of Marble Chips in: 1. Trial 1: 3.998 grams 2. Trial 2: 3.988 grams Na2CO3 + 2HCl → 2NaCl + H2O + CO2 1. Sodium Carbonate (Powdered) 2. Carbon Dioxide will be the gas collected 1. 2 Trials will take place 1. Mass of Sodium Carbonate 1. Trial 1: 0.504 grams 2. Trial 2: 0.505 grams Apparatus: 1. Eye-Protection – 1 pair of Safety Glasses 2. 1 pair of Scissors 3. 1 Electronic Scale 4. 1 Conical Flask (100cm3) 5. 1 Single-holed rubber bung and delivery tube to fit conical flask 6. 1 Measuring cylinder (100cm3) 7. Stopwatch Chemicals: 1. 12cm of Magnesium Ribbon 2. 550 cm3 of Hydrochloric Acid 3. Marble Chips 4. Sodium Carbonate (Powdered) Method: 1. Set up apparatus as shown 2. Fill the conical flask with 50cm3 of HCl 3. Insert the end of the syringe into the hole on top of the stopper 4. Add the magnesium ribbon 5. Seal the flask with a rubber stopper as quickly as you can, at the same time have someone else present to start the stop watch once the magnesium ribbon has been added to the hydrochloric acid 6. As the reaction takes place, note down the time it takes for the gas collected to reach a multiple of 5 (i.e. 5mL, 10mL †¦.50,55,60,65 etc) 7. Keep measuring until the reaction has stopped, or you are unable to measure anymore 8. Repeat each experiment 3 times, just to be sure the data collected is accurate 9. At step 4, replace the underlined compound with the next compound after one experiment is completed Conclusion Unfortunately I was unable to create a graph using time as the independent variable, because the lab that I had utilized did not have the equipment available to accurately to record the data if time were to be the independent variable. Another factor that played into my decision was the fact that the smallest calibration of the glass syringe I used was 5 cm3. Since the only visible measurements shown on the syringe were multiples of 5, it would only seem reasonable that I switch around the variables, making time the dependent variable, and the volume collected the independent variable, since I couldn’t exactly measure how much gas would be collected every 5 seconds; otherwise the relationship the graph would depict would be completely incorrect. As you can see on the graphs, the slightly steep slopes show when the reaction is the quickest, as it should be in the beginning. The curve shows the reaction slowing down, but unfortunately the curve continues. This is because the reaction is still taking place. I was unable to record the rest of the data because the measuring tools that were available weren’t able to record to such a high degree. In some cases though, like in the powdered sodium carbonate experiment, the reaction began so quickly that I wasn’t able to record the time in most cases, so I just stuck with those that I had managed to note down. In other cases, there were so many distractions in the lab that it was difficult to remain focused. My classmates kept removing some if the items that I was using. The idea was to see how the rate of reaction changed when the surface area of a substance was increased. Initially, my plan was to react magnesium ribbon and magnesium powder with 1 mole of Hydrochloric acid; so I could compare and contrast how the surface area of the substance affected the rate of reaction. I had planned to keep everything about the two substances the same. Its element, mass, the amount of Hydrochloric acid I was going to react with it; the only thing different would be its surface area. Unfortunately the Lab didn’t have any available. So I decided to do the same experiment to Calcium Carbonate, this time using marble chips and powdered calcium carbonate. To my dismay I found that the powdered calcium carbonate wasn’t reacting at all. So I had to change it to sodium carbonate. There is skepticism about using different elements, seeing as they have different orders of reactivity. These factors, including the concentration of the acid used, could also affect the rate of reaction. However, the same acid concentration was used for all experiments, in all trials; so we can dismiss that. However, sodium is much higher up the reactivity series than calcium, which is higher up the reactivity series than magnesium. This is the problem with this experiment; the elements positions in the reactivity series could have really altered the rate of reaction. However, the experiments still prove that when the surface area of a substance is increased, the rate of reaction increases as well. This happens because, when two substances react only the surface particles of the substances can come into direct contact with the reactant particles. Increasing a substance’s surface area, like turning big solid chunks of calcium carbonate into powder, leaves more solid particles available to react. The more particles available to react at one time, the faster the rate of the reaction. Like this: Only atoms on the surface can react If you break the substance down, more atoms are exposed and ready to react. Evaluation Considering the lack of material available, I think I was able to manage the experiment fairly enough to produce results. However, I am not pleased with the factors that may or may not have affected my results, and the circumstances in which I had to switch my variables around. Therefore I would like to state a few things I would like to alter, if ever I got the change to do this experiment again. 1. Apparatus 1. Next time, instead of using a stopwatch, I would like to use a digital device, like a laptop for example, that was somehow connected to the glass syringe, which was programmed to record the volume of the gas collected every 5 seconds. This time the graph would turn out the way it should be. 2. Instead of using a measuring cylinder, I would replace it with a burette, as it takes more accurate measurements of liquids. 1. Chemicals Used 1. I would try and used the same element next time; the only difference would be the surface area. For example, if I used magnesium, to study the effects of surface area on the rate of reaction, I would only you magnesium ribbon and magnesium powder. Studying different elements with different reactivity’s would dismiss any data already collected because an element’s position on the reactivity series may also determine the rate of reaction. Use the same element. 1. Amount of People involved in the experiment 1. If I had to do the experiment again, with the same apparatus, I think I would like to have 3 people participating in the collection of data. 1 person would be watching the syringe rise and call out to record whenever it rose, the 2nd person would time it, and the 3rd person would record it. This time, the data may be even more accurate, because no one is taking their eye off the experiment, like I was doing during my experiment just to record data. I feel that altering these aspects of the experiment would increase the level of accuracy, as to get more substantial data to calculate the order of reaction. Unfortunately with the data I have so far, I am unable to derive the concentrations of the substances I had utilized in my experiment. However, as the objective was to investigate whether or not different surface areas affected the rate of the reaction, I think that I have produced enough data to support my theory.

A Unique Perspective of The Yellow Wallpaper -- Yellow Wallpaper essay

     Ã‚  Ã‚  My perspective of Gilman’s short story, "The Yellow Wall-Paper" is influenced by a great number of different and diverse methods of reading. However, one cannot overlook the feminist theorists’ on this story, for the story is often proclaimed to be a founding work of feminism. Further, the historical and biographical contexts the story was written in can be enlightened by mentioning Gilman’s relationship with S. Weir Mitchell. And I can’t help but read the story and think of Foucault’s concept of Panopticism as a method of social control.

Economic Development Programs Essay

Within my community, there are several development programs which have been established for the purposes of making the community more directly participative in economic development. Such programs include agricultural development programs, business development programs as well as higher education economic development programs. These programs will be addressed in this paper, with specific attention to the key actors/players in the programs, the short and long term goals of these programs, and also the political and economic issues they face in the process of promoting economic development in the region. Agricultural finance programs To begin with, there are special loan programs for new ranchers and farmers in this region, the most infamous one being the Aggie Bond Beginning Farmer Loan Programs. Through Aggie Board Loan Programs, the state helps the newly established farmers in the region to obtain loans for purchasing land and equipments, for breeding farm animals and for the construction of farm buildings (NCOSAFP, 2010). The main players/actors in Aggie Bond Program include the lending institutions (which are in collaboration with the state administration), state administration itself—playing the role of assisting beginner farmers and ranchers to obtain low rate interest loans which are exempt from federal income tax—and the ranchers/farmers who participate in the program. The federal government is also indirectly involved in these programs since it is the one that facilitates the provision of tax exemption on the interest income. Besides obtaining loans at reduced interest rates, the financial risks on loans solely rest with the lending institutions which have established for these purposes (NCOSAFP, 2010). The short term goals of Aggie Bond Programs are to act as the capital base for individuals or partnerships within the state who desire to engage in ranching, farming or both, but lack adequate financial resources to do so (NCOSAFP, 2010). In so doing, they provide all the necessary financial resources to individuals and transfer the credit decisions to the lending institutions. On the other hand, the long term goal of Aggie Board Programs is to facilitate economic growth and development within the state and the nation at large, through optimum utilization of the agricultural resources within the state and taking advantage of the tax-exempt provisions by the federal government. The program also aims at encouraging the spirit of entrepreneurship within the state through assisting potential entrepreneurs in the agricultural sector to unleash their potential (NCOSAFP, 2010). The key economic problem that the actors in these programs face is mostly the failure of the farmers to repay loans granted due to unproductive farm activities or catastrophes which damage the farming/ ranching establishment–especially nature catastrophes (NCOSAFP, 2010). This becomes a setback all the players involved because the farmers undergoes serious financial losses, the lender incurs bad debts, the state and the federal government loses the potential economic contribution from the entrepreneur. Political issues on the other hand arise from the Aggie bond allocations and apportionments among the lending bodies. For instance, after a serious debate on the farm bill, the maximum bond allocation was increased from $469 200 in 2009 to 470,100 this year and the actors have been involved in political discussions regarding the meager increments and how it would be equally apportioned to the lending institutions (NCOSAFP, 2010). Business financing programs The other type of economic development programs are the business financing development programs. These programs are so closely related to the Aggie Bond Programs in that they offer loans for many kinds of business businessmen in the state. However, there is a slight different from the one discussed above because this program finances both established as well as new business-people in the industry. For the new entrants, capital is provided while for the already existing business people, the required funds for activities such as expansion and boosting for those experiencing serious financial traps is availed (OK Commerce, 2010). The actors in these programs are established lending institutions and the business community. They include; Economic Development Administration, the Bureau Of Indian Affairs Loan Guaranty Fund, The Industrial Finance Authority, Capital Access Program, and the Linked Deposit Loan Programs. The short term goals of these programs is to provide short term business financing to the business community to solve short term cash problems, while the long term goals are to offer long term low interest loans to major business persons/ institutions to solve serious and long range financial issues (OK Commerce, 2010). Mostly, these programs do not face much political issues as compared to the economic issues which are tied to the unsecured loans and competition. While the unsecured loans may sometimes compel the lending institution to file cases in the legal system against errant and faulting business people, the competition from other existing lending institutions makes them too congested in the estate (OK Commerce, 2010). Higher education programs The state also has a Higher Education Economic Development Program. This program is designed in such way as to generate partnerships between businesses and higher education institutions within the state in order to nurture higher learning via State Regents’ Economic Development Grants. Nominations are made from the institutions and assessed by State Regents’ staff committee. Submissions are made just once for every partnership, and a limit of twenty five recognitions can be made annually (OK Highered, 2010). The actors in this program are basically partnering institutions, which usually pay $500 coordinated by the state regents. The money provided is used for internships for students of institutions to work in the enterprises of partnering business, faculty externships with partnering businesses, tuition waivers to partnering businesses’ staff members, and development of partnerships with supplementary equipment, supplies and materials (OK Highered, 2010). The short term and long term a goal of this program is the same: to facilitate economic development through partnering for the purposes of higher education. In so doing, the partnering members are able to assist each other in catering for the expenses of higher education to ensure that none is left out. In addition, they promote economic growth growth of the member businesses through materials and other kinds of supplies using the funds contributed by each partner (OK Highered, 2010). Just like the other economic development programs mentioned above, this program also faces a number of political and economical problems in its endeavors to accomplish goals and objectives. On the economic part, the program currently has a capacity of twenty two member universities and sometimes, the resources available from the partnership funds cannot meet all the needs of the partners: consequently, the process of assisting members cater for higher education needs has to take longer than the members desire (OK Highered, 2010). This basically, has the result of slowing down the accomplishment of goals and also sometimes results to withdraw of some impatient partners. In addition, the members have too much higher education needs such that the partnership has only to cater for a small percentage of the required amounts. In so doing, the economic goals are partially and not wholly accomplished. Politically, the program is not affected by external politics, but rather by internal politics among the members which mostly results from conflicting interests amongst the members and also in the selection of the leaders who will foresee the management of operations and finances (OK Highered, 2010). However, such issues have been solved successfully within the environs of the partnership. References NCOSAFP (2010). Types of state agricultural finance programs.

Jeff Bezos strategy was to offer its clients lowest possible prices and world leading customer experience thereby becoming the biggest bookstore and the leading global online service in the world. Don’t waste time! Our writers will create an original "Business Strategy of Amazon: A Summary" essay for you Create order They wanted to remain customer focused and innovate continuously to improve the online shopping experience whereby customers can buy anything online. Even though there was stiff competition from Barnes and Noble, had the advantage as the â€Å"first mover†. Between the year 1997 and 1999, it entered into promotional and strategic relationship with internet players like Yahoo. com, America Online, Excite and Dell Computers which reinforced Amazon. com’s position as the leading online bookseller. With growing customer expectations, Amazon. com introduced new products like Amazon. om Advantage, Amazon. fr, and Amazon. com Kids and also expanded operations in Germany and UK. During this phase it also went into acquiring a series of companies like Bookpages, Internet Movie Database, Junglee and Planetall for e-commerce; and announced strategic investments in companies like Drugstore. com, Della James, Pets. com. Most importantly Amazon launched its most successful music sto re with over 200,000 CD’s were being offered. However in April, 2000 led to heavy losses within Amazon. com resulting in cost cutting and closing of service centers in Hague, Netherlands, Seattle. However from 2001 onwards positive signs had begun to show with Amazon recording highest quarter sales over $1b in the fourth quarter. In 2002 by opening a website in Canada, it became the company’s 6th website and thus expanding its international sale as well. Amazon’s biggest achievement was to receive from the American Customer Satisfaction Index in 2002 the highest score in customer satisfaction ever recorded. Hence Amazon’s success shows its willingness to innovate, invest, acquire and form strategic alliances with other companies that offered products, technology and application for better customer experience. Business Model: A business model is an explanation of the operation of the business which comprises all the element of business, the task carried out in the business and includes the way the business generates revenues (Rayport, 2002). The business model of Amazon. com – a U. S. A based multinational e-commerce company, is well established because of the delivery of goods, services and information provided to its customers. Continuous development of operational efficiency will lead to sustainable competitive advantage of Amazon. com. This model takes title to the newly manufactured products that they sell and often rely on third party. Amazon. com requires third party source, such as Borders. com and Barnesandnoble. com, to maintain its sufficient supplies. To check whether the existing business model will work in future or not we have to do SWOT analysis. Strength: ? The company themselves developed key competencies in technology development, computer science and software. ? Variety of products available at low prices. ? Strategic alliances invest or acquire other companies that offered developed technology, applications, products or services that fitted its existing business model. High in customer satisfaction. Weakness: ? Amazon. com being in the highly volatile sector, to achieve sustainable competitive advantage it has to constantly revise its strategy and business model. ? Concentration of Amazon. com was on auctions which was a small part of their business. ? Due to issues in broadband/internet in developing countries, huge market is untapped. Threats: ? Concentration of Amazon. com was on auctions which wa s a small part of their business. ? In Amazon. com, Kindle – its e-book reader has a high value. Since Amazon builds the Kindle and sells digital books, Amazon is placing a large bet on the success of its Kindle franchise. However, Sony and IREX have released or are currently releasing competitor e-book readers. ? All high revenue generated or profit making business attracts competitors. Amazon. com would also face competition as it is difficult to differentiate the brand because it sells the product which is available on many other online sites. Opportunities: ? Market in developing countries. ? Increasing number of internet users. By analyzing the SWOT it can be concluded that the business model of Amazon. om will work in future provided that it has to adopt strategies that will give them competitive advantage. Also the attracting factor is the increasing number of internet users in developing countries will provide the new market and new customers. Also concentrating on customer intimacy rather than customer delight would be added advantage. Customer Focus: In the case it ca n be observed that since the startup till 2004, there has been a tremendous increase in the number of customers from nearly 150 countries which has lead to the expansion of their business and also expansion in their product line. From books, music all the way to a toilet brush has been made available to customers to buy with Amazon. com. With attractive low prices, huge selections and fast delivery of the products, Amazon. com has been able to successfully cater to the needs of various customers all over the globe. Also with the increase in the number of internet usage that can be seen in exhibit 8, Amazon. com still has a wide market of customers to cater to. Therefore they should continue catering to all the people has they have been successful with their existing business model. Means to Innovate and Enhance Customer Experience: ? Amazon. com has more than 76 million customers in which they can buy any item through the internet. It has introduced the selling of the items through internet and has customer accounts of only 1. 3 million and it is trying to increase this base. To increase it should make the customers aware of the selling of items through them and the price factor should also be taken care of. ? It has a loyalty program for its customers where they can join with a membership fee, on which they would be receiving discounts on express shipping i. . fast delivery of the products which they offer this only for the US, the UK, Japan and Germany. They should also make the availability of the offer in India, China and other countries. ? To improve its business it should start its e-commerce business in other parts of the world where people use internet extensively. ? Amazon. com sells its products to the customers without revealing who the vendor of the product is; whereas the other online sellers who have tie-ups with different kinds of vendors are able to provide its customers ith lower prices. Hence, Amazon. com should reveal its vendors so that it can provide the products even more at a cheaper price. Amazon. com The Wal-Mart of the Internet? There is intense competition in running an ecommerce venture and the many fierce competitors existing makes it all the more competitive for Amazon. com. Using Amazon’s stores will further help in creating internet based business and will force to have a direct competition with these competitors emerging. As Amazon. om offers the best prices for all kinds of products and also some products do not have any shipping deals, this makes them stand out from the others and they still make a profit out of it. Wal–Mart also focuses on offering the best deals to their customers, by charging low prices they bring out an added advantage to their retail business. Amazon. com has been ent irely unique with their business model as they focus not only on a particular products but a series of products which in turn adds values to their company. There are numerous reasons why the customers prefer using Amazon. com is mainly because they can get it directly and at a low price without any additional charge deducted. As usage of internet has increased all over the world, this further helps people to make their decisions faster and they also save time when compared to buying from an Amazon. com store. Also Amazon. com offers finest return policies, most excellent shipping prices and also biggest assortment of various products of any place over the whole web. Additionally those who have an account get 2 day free shipping as well as others promising deals. Products like kitchen items, clothes, computers, etc are free from shipping charges can be bought at one go. Amazon. com had engraved itself in many areas and had captured the attention of various consumers. Looking at their statistical range, they consider using the information that they have access to and come to conclusion about how prices should be charged and how to attain the low price wholesalers that exist in the market and make their business through. Since Amazon. com has entered into different areas, mainly into different markets wholly they now have the right to sell anything over the internet as they have the entire advantage over the other existing online businesses. In conclusion, we would like to say that as Amazon. com had engulfed various businesses into one whole business wherein customers can find whatever they require and shop accordingly, they have captures a very large unit on the internet in such a way that they have created barriers for other competitors to enter the market. An attractive way to expand themselves was by making their business stable and also sustaining the needs of the customers by the prices they set for their products. Recommendations: ? Being a competitive market and expenses being high, offering free shipping of books might affect the future financial position of the company. So Amazon. com should charge for shipping at a discounted rate. ? Amazon. com might also consider introducing Spanish version of their website since Hispanic Americans and the Latinos are the fastest growing ethnic group online. ? In order to have a competitive advantage and triple its sales Amazon. om might consider introducing referral programs for the its customers, wherein discount coupons would be given to those customers who bring in approximately 10 new members to their website. Also discount would be given to the new members who were newly referred in order to encourage them to start buying. References: About Amazon. com, (Jan 31st, 2010).
