Problem: Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation. 2H2O2 (aq) → 2H2O (l) + O2 (g) The activation energy for this reaction is 75 kJ mol-1. The enzyme catalase (found in blood) lowers the activation energy to 8.0 kJ mol-1. At what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25 °C?

Problem Details

Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation. 

2H2O2 (aq) → 2H2O (l) + O2 (g) 

The activation energy for this reaction is 75 kJ mol-1. The enzyme catalase (found in blood) lowers the activation energy to 8.0 kJ mol-1

At what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25 °C?
