## rate laws

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

### rate laws

Are rate laws simply referring to the rate at which a concentration increases or decreases? What's the difference between integrated versus differential?

Also what is/are the underlying key concept(s) that we should take away from the various rate laws?

I think the difference is just that the Differential Rate Law uses derivatives, but we want to make the analysis easier/"better" so to get rid of the derivatives we integrate. So, the Differential Rate Law expresses the rate of the reaction as a function of change in concentration over time. The Integrated Rate Law expresses the rate of the reaction as a function of the initial concentration and actual concentration over time.
