Answer to Question #202651 in Physical Chemistry for JOHN

Question

A metal M exists in two forms M^b+ and M^a+ (b > a). When a current of 2 A is passed through a 1 L aqueous solution of 0.01 M M^b+ for 965 s, 0.005 mol of the metal was deposited at the cathode while the concentration of M^a+ in solution was found to be 0.005 M. Assuming that the reduction process takes place stepwise and equal moles of electrons are consumed in both the reduction reactions, find the value of a × b.
