The hydrolysis of urea to ammonia plus CO2 normally has an activation energy of 125 kJ/mol at 294 K, but when the urease enzyme catalyzes the reaction it lowers the activation energy to 46 kJ/mol. By what factor does this increase the velocity of the reaction? The rate constant equation might be helpful here, where k = A·e(-ΔG°‡/RT) and A = 6.12 x 1012 s-1. Look at both kcat and knon, finding the ratio between the two
