Chemistry Exploration Topic: determining the activation energy of a chemical reaction Research Question: To study the effect of temperature on the activation energy of the chemical reaction ICT: Microsoft Word Autograph Microsoft Excel Introduction This experiment is designed to help in estimating the activation energy of the rate-limiting step in the acid catalyzed reaction of acetone with iodine. This is achieved by measuring the reaction rates at different reaction temperatures over the experiment. Once the raw data is obtained I will analyze the data with the help of an Arrhenius plot. This is a tool used in determining the activation energy of chemical reactions. Here the natural logarithm of the rate of reaction is expressed as a function of the temperature and then fit into the Arrhenius equation to give a linear model. The slope of the line is then used to calculate the activation energy. The details of of the molecules. Consequently these molecules are able to move faster and the probability of collusion with other molecules is increased. Hence the time taken for the reaction to be completed is reduced and the rate of reaction increases. Conclusion The experiment was conducted with the aim of being able to determine the activation energy of the reaction. Additionally the effect of temperature on the rate of reaction was also to be investigated. Careful analysis of the data enabled me to estimate the activation energy as 70.96 kJ/mol. This value shows the amount of energy that is required for the chemical reaction to start. Aside from the activation energy I was able to establish the relationship between the rate of chemical reaction and temperature. From the it is clear that the rate of reaction is directly proportional to the temperature due to the positive value of the activation energy. [...]
This is an IB chemistry exploration. The fie attached contains most the work and i just need someone to finish the remaining the work and improve the work already done by me.
