The enzyme urease catalyzes the reaction of urea, (nh2conh2), with water to produce carbon dioxide and ammonia. in water, without the enzyme, the reaction proceeds with a first-order rate constant of 4.15 ×10−5s−1 at 100 ∘c. in the presence of the enzyme in water, the reaction proceeds with a rate constant of 3.4 ×104s−1 at 21 ∘c. if the rate of the catalyzed reaction were the same at 100 ∘c as it is at 21 ∘c, what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions?
