### What is the order of the reaction?

What does the "order" of a reaction mean? What is the difference between a first, second, third, or zeroth order reaction?

The order of your reaction is the n value. It shows up in the differential rate law where
Rate=k[R]^n (so n=0 in a zero order reaction, n=1 in a 1st order reaction, etc)

If there are multiple reactants, you add up the exponents to find the total order of the reaction.

The order of a reaction is the sum of the individual orders with respect to each reactant, and it tells you about the relationship between reactant concentrations and rate.

In class we also discussed the different plots that go with each reaction:
First order means a straight line plot of ln[reactant] vs time
Second order means a straight line plot of 1/[reactant] vs time
Zero order means a straight line plot of [reactant] vs time

[reactant] means concentration of the reactant
