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 Γ10β5sβ1 at 100 βc. in the presence of the enzyme in water, the reaction proceeds with a rate constant of 3.4 Γ104sβ1 at 21 βc. if the rate of the catalyzed reaction were the same at 100 βc as it is at 21 βc, what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions?
