Consider a reaction that is composed of two consecutive elementary reactions: A --ka--> I ---kb---> P With ka = 0.120 min-1, and kb = 0.012 min-1. Assume that the intermediate I is the compound of interest to you. At what time is the concentration of I the greatest, ie. after what time should you stop the reaction to obtain a maximum of I?
