The activation energy of a certain uncatalyzed biochemical reaction is 46.7 kJ/mol. In the presence of a catalyst at 39ºC, the rate constant for the reaction increases by a factor of 2030 as compared with the uncatalyzed reaction. Assuming the frequency factor A is the same for both the catalyzed and uncatalyzed reactions, calculate the activation energy for the catalyzed reaction. Activation energy = kJ/mol

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.
The uncatalyzed decomposition of CH3CHO has an activation energy of 188 kJ mol-1. I2 catalyzes the...
The uncatalyzed decomposition of CH3CHO has an activation energy of 188 kJ mol-1. I2 catalyzes the reaction, and at 600 K the catalyzed reaction is ten million times faster than the uncatalyzed reaction. Therefore, assuming that the pre-exponential factor, A, is the same for both the uncatalyzed and catalyzed reactions, the activation energy of the catalyzed reaction is, in kJ mol- 80.4 B. 71.0 C. 108 D. 117 E. 172
