Question
Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the reaction equation
2H,0, (aq)
2 H,O(1) + 0,(g)
The activation energy for this reaction is 75 kJ-mol-. 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?
T =
507.5
K
