A popular chemical demonstration is the “magic genie” procedure, in which hydrogen peroxide decomposes to water and oxygen gas with the aid of a catalyst. The activation energy of this (uncatalyzed) reaction is 70.0 kJ/mol. When the catalyst is added, the activation energy (at 20.ºC) is 42.0 kJ/mol. Theoretically, to what temperature (ºC) would one have to heat the hydrogen peroxide solution so that the rate of the uncatalyzed reaction is equal to the rate of the catalyzed reaction at 20.ºC? Assume the frequency factor is constant, and assume the initial concentrations are the same.

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.

The activation energy for a reaction is changed from 184 kJ/mol to 58.1 kJ/mol at 600. K by the introduction of a catalyst. If the uncatalyzed reaction takes about 2574 years to occur, about how long will the catalyzed reaction take? Assume the frequency factor A is constant and assume the initial concentrations are the same.
