We’re being asked to **determine the unit for the rate constant (k)** of a third-order reaction

In this case, we can solve for the units of k using M as concentration and t as seconds. We can establish the equation as:

$\overline{){\mathbf{rate}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{k}}{\mathbf{\left[}\mathbf{A}\mathbf{\right]}}^{{\mathbf{3}}}\mathbf{}}$

The units of the rate constant for a third-order reaction are:

a. 1/M^{3}•s

b. 1/M•s

c. M^{2}•s

d. 1/M^{2}•s

e. M^{-3}•s
