## slow step

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

### slow step

how can you tell which step in a rxn is the rate-determining step/slow step? i get it by looking at a graph or something, but what if you only have the rxn in front of you?

I think the problem will indicate that which reaction is the slow step.

If you are given the experimentally determined rate law or something like that, you can find an intermediate step that matches that rate law, making that the slowest step.

For the slow step the actual reaction that determines which step is the slow step is the intermediate reaction right before the slow step.

### Re: slow step

The molecule involved in the slow step is what determines the rate generally.
