Order of a Reaction

[Jessica Helfond 2F]

How can you tell what the order of a reaction is?

[Maddy Mackenzie]

In order to tell the order of a reaction, the problem will either have to state it or they will provide experimental data for you to use the method of initial rates to determine the order of the individual reactants. Then the order of the reaction is the sum of all the individual orders of the reactants. For example if you have A + B --> C and you experimentally determine that the order of A is 1 and the order of B is 1, then the overall order of the reaction is 1 + 1 or 2.

another way to tell the order of the rxn is if the question gives you k. Based on the units of k, you can tell the order of the rxn.
