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

### Which law?

How do we know when to use each rate law? Will we have to be able to recognize it or will the question tell us?

We will most likely have to determine the order of the reaction, but we will be given the necessary information to determine this.

### Re: Which law?

Sometimes the question tells you which order it is, and from there you can determine the rate. Otherwise, there should be sufficient data given to dtermine which rate to use.
