A and B react according to the following reactions, which lead to production of desired (D) and undesired (U) species: A+BD,r1=k1CACBD+BU,r2=k2CDCB You have two beakers, one containing A and another containing B. If you wish to maximize the formation of D, in what manner would you mix the reactants and at what rate? Justify you answer. Note: You are free to alter the rate during the mixing.
