## Molecularity vs Order

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Molecularity vs Order

Is the molecularity and order the same for elementary reactions and the overall reaction? If not, what's the difference?

### Re: Molecularity vs Order

Molecularity is just the number of molecules that come together to form a reaction so I think there could be different molecularities for the elementary reactions and the overall reaction but probably not often. The order of a reaction depends on the pathway of the overall reaction so I would think it'd be the same in both.
