WebSo writing the same rate law with just the units: M/s = k*M, we see that for both sides of the equation to have the same unit the rate constant must be 1/s or s^(-1). This is because M*1/s = M/s, the same unit as the rate's unit. The same kind of logic goes into figuring out the other rate law constant's units. Hope that helps.
