### The Rate Limiting Step

If the first step is the rate limiting step and it is a reaction that goes in the forward and reverse direction, why isn't the overall reaction rate the forward reaction rate over the reverse reaction rate in the rate limiting step?

### Re: The Rate Limiting Step

In addition to this, why must you perform the pre-equilibrium approach specifically if the second step of the reaction is the limiting step?
