Abstract
A kinetics experiment for general or physical chemistry students is presented. The common iodine clock reaction is modified and the initial rate method is used to observe the role of catalyst in the reactions through activation energy calculations. An experimental procedure is designed such that students can determine the order with respect to each reactant and evaluate the mechanism that has been previously reported for this reaction. Furthermore, students use experimental results to calculate the rate constants of the uncatalyzed and catalyzed (independent of the uncatalyzed) reactions.
