### Using pre-equilibrium approach

If the first step in a process is the slow step and its rate does not match the overall reaction rate, is it definitely an invalid proposed mechanism?

From my understanding that is correct!

### Re: Using pre-equilibrium approach

Should we always start problems using the pre-equilibrium approach?

### Re: Using pre-equilibrium approach

The pre-equilibrium approach should be used on problems where the slow step is not the first step in the reaction and the reaction rate of the later step contains and intermediate. You could also try using the steady state approach, but this is much more complicated and difficult.
