slow step and fast step

why does the slow step not influence the overall rate?

Re: slow step and fast step

It's actually the opposite. The fast step does not affect the overall rate because the overall reaction is only as fast as its slowest step. No matter how fast other reactions run, the overall reaction can't be completed until the slowest step is completed. Therefore, the rate of the overall reactions is equal to the rate of the slowest step.

Re: slow step and fast step

The slow step is the rate-determining step.

Re: slow step and fast step

The slow step actually does determine the overall rate, since the reaction is only as fast as its slowest step
