AP Chemistry Rate of Reactions Lesson 7 - Reaction Mechanisms, elementary step and fast equilibriums

In this final lesson of the AP Rate of Reaction unit, we will study what occurs between the beginning and end of a reaction. We will break down reactions into a series of elementary steps. The slowest step will correspond to the orders in the rate law.
