### Pre Equilibrium Approach

When would one use the pre-equilibtium approach. What would the question be asking? I can't seem to find a problem where it explicitly asks for one to use the approach to solve for something?

### Re: Pre Equilibrium Approach

Usually, we use a pre equilibrium approach when the reaction is separated into a few steps in which the a fast step is followed by a slow step. In this case, we can assume that the faster step reaches equilibrium.

Typically we are given a fast step and slow step when asked to use this approach

### Re: Pre Equilibrium Approach

We use the preequilibrium approach in order to get rid of intermediates in the final rate law
