What are the units of the zero, first and second order?

Zero-order should be M/s. First-order should be s^-1. and second-order should be M^-1 * s^-1.

The unit of k basically just needs to lead to the unit of concentration/second
A zero-order reaction means that k has a unit of M/s
A first-order reaction has a k with unit 1/s
A second-order reaction has a k with unit 1/M*s

Zero order: mol.L^-1.s^-1 or M/s
First order: s^-1
Second order: L.mol^-1.s^-1

I believe it was a homework question on the 6th edition #9 under the kinetics chapter

zero order: M/s
1st order: 1/s
2nd order : 1/(M*s)
