The second-order rate constant is defined as k = k[M][N]/([M] + [N]) where [M] and [N] are the concentrations of the reactants. The units of k depend on the units of [M] and [N]. Since the order of the rate law is 2, the units of [M] and [N] are both M (molarity). Therefore, the units of k are 1/M·s, which is choice B.
