Differential rate law

What is the differential rate law and when will it be used?

For a reaction aR --> bP, the initial reaction rate is k[R]n. I believe in class we used this to compare two or more initial rates, but there could be more uses discovered later on in lecture.

I think its main use is to integrate this and use it as the integrated rate law.

Deriving the integrated rate law from the differential rate law is more useful to us because we can plot ln[A] (and the natural logs of any other reactants present) against time and figure out the overall order of a reaction. As we discussed today, if the graph is linear, you know you are dealing with a first-order reaction.
