## Writing the Rate Law

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

### Writing the Rate Law

Do we have to write the phase of the molecule when writing the specific rate law?

No, but it is good to know that liquids and solids don't get put in the rate law and that the rate law is only defined by gasses and aqueous molecules/ atoms. So most likely the reactants expressed in the rate law will be in the same phase.

I don't think we do, especially since rate laws simply deal with the concentrations of substances
