molecularity

[Felicia Fong 2G]

Do you determine the molecularity of a reaction by number of reactants? For example, if NO+NO yields N2O2 then it is bimolecular because there are two reactants?

[Jakob von Morgenland 2C]

You can determine the molecularity by looking at the number of molecules that participate/are used in the rate-determining step/rate law.

[aaron tang 2K]

Yes you do.
A -> P unimolecular
A+B -> bimolecular
A+A -> bimolecular

[Kailey Brodeur 1J]

You are correct that molecularity can be determined by the reactants, but we have to remember that this concept only relates to elementary reactions and doesn't apply to overall reactions.

[Renee Delamater 2H]

Even though there are only NO molecules in the problem, using 2 of the NOs makes it bimolecular.

[KayleeMcCord1F]

You can determine molecularity by the number of molecules of reactants.

[Arshpreet Sandhu 1B]

Yeah, you calculate molecularity by the number of reactants in a reaction.
