Product Details

College Level Classic General Chemistry Experiment Students study the kinetics of a clock reaction involving the oxidation of iodide ion by bromate ion in the presence of an acid. First, students study the effect of concentration on the rate of reaction to determine the order of reaction for each reactant and the rate constant. Second, the activation energy is determined by varying the temperature, measuring the rate, and calculating the rate constant at different temperatures. Finally, the effect of a catalyst on reaction rate is studied. Students gain valuable experience with kinetics calculations and microscale techniques. They also understand why the changes in concentration, temperature, and the use of a catalyst are made in each part of the experiment, and how these changes lead to the calculated quantities. Complete for 24 students working in pairs. Two reusable 12-well reaction strips are recommended for each student group and are available separately.
