(c) Hydrogen peroxide is sold commercially as a 30.0% solution. If the solution is kept at room temperature (25C), how. long will it take for the solution to become 10.0%H2O2 ? (d) It has been determined that at 40C, the rate constant for the reaction is 1.93103min1. Calculate the activation energy for the decomposition of H2O2. (e) Manufacturers recommend that solutions of hydrogen peroxide be kept in a reltigerator at 4C. How much longer will it take a 30.0% solution to decompose to 10.0% if one follows the manufacturer's recommendations? (f) The rate constant for the catalyzed decomposition at 25C is 2.95104min1. 1. What is the half-ise of the catalyzed reaction? 2. What is the rate of the catalyzed decomposition of 0.500MH2O2 ? 3. How much faster is the rate of the catalyzed reaction compared to that of the uncatalyzed decomposition
