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

### Writing out states for rate laws

Do we have to rate out the states of the reactants in rate laws? In the book, the states of the reactants (gas, solid, liquid) are not included in the rate laws.

I'm pretty sure that we don't have to.

I think only the concentration should be included.

Just make sure to include units

I think we do not have to do so. But it is necessary to make sure that the units are all correct
