Chemistry Help, Thank you!

A chemistry book lists the rate constant for a reaction as 186.1 3 M s. What is the overall order of the reaction?

You can tell from the units on the constant. The unit for this rate constant is M/s. That corresponds to a zero order reaction. Here is a link you can look at to show you what I mean.
