## intermediate molecules

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

### intermediate molecules

Why are intermediate molecules not included in the rate law? Thank you!

### Re: intermediate molecules

They are not part of the overall rate law because they are produced in one step and consumed in another, later step.

### Re: intermediate molecules

Intermediate molecules are not included in general rate laws because only reactants are, but they can be included if you break down the reaction mechanism and look into the rate for each step.

Intermediate molecules are not a part of the overall reaction, as they are produced and consumed in separate elementary steps of the reaction.
