The enzyme carbonic anhydrase catalyzes the reaction CO2(g)+H2O(l)−→−HCO3−(aq)+H+(aq).CO2(g)+H2O(l)→ HCO3−(aq)+H+(aq). In water, without the enzyme, the reaction proceeds with a rate constant of 0.039s−10.039 s−1 at 25°C.25 °C. In the presence of the enzyme in water, the reaction proceeds with a rate constant of 1.0×106s−11.0×106 s−1 at 25°C.25 °C. Assuming the collision factor is the same for both situations, calculate the difference in activation energies for the uncatalyzed versus enzyme- catalyzed reaction.
