4. [Chang, 10.27) The activation energy for the decomposition of hydrogen peroxide: 2H2O2 (aq) → 2H200 + O2(g) is 42 kl.mol-1, whereas when the reaction is catalyzed by the enzyme catalase, it is 7.0 kJ. mol-1. Calculate the temperature that would cause the nonenzymatic catalysis to proceed as rapidly as the enzyme-catalyzed decomposition at 20°C. Assume the pre-exponential factor to be the same in both cases.
