### pre equilibrium approach

When do we know to use the pre equilibrium approach?
Thanks

### Re: pre equilibrium approach

The pre-equilibrium approach is used to find an expression for the rate of product formed. It is used when the first step of the reaction is the faster step. This is in contrast to the steany state method in which the first step is the slow step. Furthermore, the pre-equilibrium approach is used when an intermediate is formed.

### Re: pre equilibrium approach

do we do pre equilibrium basically any time the slow step is not the very first step?
