If the unit for a particular rate constant is M^{- 1}sec^{- 1}, what is the order of the rate law?

Question

Quizplus · Accepted Answer

The order of the rate law is equal to the sum of the exponents on the concentration terms in the rate law. From the given unit of the rate constant, we can see that there are two concentration terms, one raised to the first power (U1P1) and another raised to the zeroth power (S1P0). Therefore, the order of the rate law is 2nd order. Option C is the only answer that is 2nd order.
