## Rate Determining Step

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

### Rate Determining Step

Hi,
Is the rate-determining step the same as the slow step? Does this reaction ultimately define our rate?

Yeah I think the rate determining step is usually the slowest step, and it is also called the elementary step sometimes.

Yes, the step with the slowest rate is the rate determining step for the reaction!

### Re: Rate Determining Step

The rate determining step is the slow step. You can think of it this way. If two runners are tied together, one who is a track star and one who has never run before, even if the track star can outrun the slower runner, they are prevented because they are tied together. They can only move as fast as the slowest runner.

Yes, the rate determining step is the slowest step. You can think of it like the limiting reactant.
