Answer to Question #33606 in Physical Chemistry for Sumit

Question

The hydrolysis of a substrate is simultaneously catalyzed by H+ & OH- ions & also occurs spontaneously. The reaction is first order with respect to all species. Write down the expression for the rate constant. Hence show the rate is minimum when [H+] = [ {K(OH-) / K(H+)} * Kw ]^(1/2)
