## First-order reactions

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

### First-order reactions

Are first-order reactions only with reactions that have 1 reactant? I know he said we'd get to larger reactions later, but I was just wondering about this.

I'm not completely positive, but I believe that there can be more than one reactant for a first order reactant, we just haven't covered those yet in this course

No I'm pretty sure there can be more than one reactant. First order just means that if we increase a reactant, the product will increase by that amount as well. Usually though, we look at one reactant at a time.
