### Catalysts

Do catalysts have to be added to the slow step in order to change the rate? Will they not affect the rate if they are added to the fast step?

### Re: Catalysts

I think it can be added to any step, but only adding it to the slow step will really change the rate of the reaction. It will both affect the activation energy barrier, but only the one in the slow step will make a difference in the rate because that is the rate determining step.
