A) The enzyme urease catalyzes the hydrolysis of urea to ammonia and carbon dioxide. The uncatalyzed reaction has an activation energy of 125 kJ/mol. The enzyme catalyzes a mechanism that has an activation energy of 46 kJ/mol. By what factor does urease increase the rate of urea hydrolysis at 21 celsius? B) True or False: A catalyst increases the rate of a reaction by changing the mechanism of the reaction such that there is a different rate law for the reaction when a catalyst is present. C) True or False: A catalyst increases the equilibrium constant of a reaction and therefore makes the products more favored. D) True or False: In order for a catalyst to function it must exist in the same phase as the substrate.
