How does one determine the molecularity of a reaction?

You can determine molecularity by looking at the number of molecules/ions/atoms that are participating in the rate determining step of a reaction.

For example, the reaction:
[A]---->[P] would be unimolecular because there is only one molecule on the reactants side
[A] + [B]----->[P] AND [A]^2----->[P] would be bimolecular since in each case there are 2 molecules on the reactant side
[A] + [B] + [C]----->[P] AND [A]^2+[B]----->[P] would be termolecular since there are 3 molecules on the reactant side
