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 Ã10â5sâ1 at 100 âC. In the presence of the enzyme in water, the reaction proceeds with a rate constant of 3.4 Ã104sâ1 at 21 âC.
If the rate of the catalyzed reaction were the same at 100 âC as it is at 21 âC, what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions?

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 
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 enzyme-catalyzed reaction.
