Deriving the differential rate law

Postby DanielLee3H » Sun Feb 19, 2017 6:18 pm

How did we get from the general rate equation (-1/a)*d[A]/dt to the differential rate law k[R]^n?

We didn't.

What we did do is state that:

(-1/a)*d[A]/dt = k[R]n which is the differential rate law

Oh oops. Thank you. Also, the method of initial rates and the integrated rate law are different ways to find the reaction constant. Do they just give you different ways of modeling the reaction rate? And you can use both to find any reaction rate, whether it is the slow step or the overall reaction?
