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