The rate law equation is Rate = k[X][Y]. The concentration of [X] and [Y] are in units of M (molarity). The rate has units of M/s (molarity per second). Therefore, the units of k should cancel out the M term in the rate units, leaving only 1/s (per second). The only choice that has units of 1/s is C.
