# A chemistry book lists the rate constant for a reaction as 34.5 (1)/(M*s). What is the overall order of the reaction?

## Is this a trick question? Is it even possible to find the overall order with just the rate constant?

You are told the units for the rate constant $\textcolor{b l u e}{\text{k}}$ as ${M}^{- 1} {s}^{- 1}$ or $\frac{1}{M \cdot s}$. This is a second order reaction.
Here is a good link to use to read up on units for first, second, and third order reactions.$\to$Units for first, second, and third order reactions
