1. The rate law for the reaction between catalase and hydrogen peroxide can be written as Rate = k [H2O2] x [catalase]y . A catalase solution of unknown, but constant concentration is prepared. Can the partial order with respect to the peroxide (x) be found using this catalase solution? If so, how would you do it? Describe in detail the steps you would take or show a calculation.

2. At 20.0^oC, a student studying the catalase-catalyzed decomposition of hydrogen peroxide obtained an initial rate of formation of oxygen of 0.46 mL s -1 . At 30.0 and 37.0^oC, the student obtained initial rates of 0.63 and 0.73 mL s -1 . What was the value of the activation energy that the student obtained?

3. A student obtained the following data for the iodide-catalyzed decomposition of hydrogen peroxide in a trial at 30.0^oC: Time (s) Pressure O2 formed (kPa) 0.20 103.63 0.40 104.19 0.60 104.75 0.80 105.30 1.00 105.86 What initial rate was the student able to calculate for the iodide-catalyzed decomposition of hydrogen peroxide at 30.0^oC?

4. For an experimental study of the kinetics of hydrogen peroxide decomposition in which the pressure of oxygen or volume of oxygen is monitored as a function of time, what should the volume of oxygen collected or the pressure of oxygen be at time zero? Do you expect your plot to pass through the origin? If so, why? If not, why not?
