Temperature dependence of the rate constant | |
 |
|
|
This week you will measure the rate of reaction at different temperatures to determine the activation energy of the reaction. Use ice to lower the temperature of your water bath (left). Watch the temperature carefully, so that it remains constant throughout the reaction. Add hot water (right) to make a temperature bath above room temperature. Aim for 4 different temperatures between 5 and 40°C. Don't worry about reaching a particular temperature, but when the temperature of your bath stabilizes near your target, record the temperature and begin a reaction. Modify your reaction conditions so that reactions will be complete in a time between 10 and 30 minutes.
