### The Units of k (rate constant) for second order

As I was trying to figure out the units for the rate constant (k) for second order, using the integrated rate law, I got that the units were 1/M^-1*sec^-1, are these units correct? If so, could an explanation be provided as to how they can be understood conceptually.

It is going to be that since the initial rate is measured in M/S while the [A]^2 is in M^2. So as a result, k has to be 1/(M)(s).

The units for second order reactions is M^(-1)* s^(-1), or L/(mol*s), so you are correct!
