Question

Write the units of rate constants for zero order and first order reactions.

Answer 1

For zero order reaction, the unit of rate constant is equal to the unit of the rate of the reaction. It is $\frac{\text{M}}{\text{s}}$ or $\frac{\text{mol}}{\text{L}\cdot \text{s}}$. For first order reaction, the unit of rate constant is equal to ${\text{s}}^{-1}$ or ${\text{min}}^{-1}$.
