## Substitution Reactions

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

What is the leaving group in a substitution reaction?

For substitution reactions, I thought we only replaced the intermediates

### Re: Substitution Reactions

The way I understand it, Intermediates come into the reaction as a product, and are later consumed so they do not show up in the overall reaction equation. Catalysts are reactants that speeds up the reaction and go away but show up again in the product, so they also cancel out, and do not show up in the overall reaction. They CAN, however, show up in the rate law.
