In this video, Mr. Krug shows students how to recognize a catalyst in a reaction mechanism and how to work with a catalyst in a rate-determining step when writing a rate law. He then finishes the video with some conceptual review questions about chemical kinetics.

Ap daily videos from college board can get pretty confusing but your videos help me understand these concepts far better. Thanks for helping me review!

I have a question. I’ve read online and my chemistry teacher has even said that the catalyst should be in the rate law equation if it’s in the rate determining step (slow step). Bcuz it does affect the rate, even though it isn’t represented in the overall equation. Is this correct or should I just get rid of it when answering a rate law question.

3:26 so I’m confused, college board questions have the rate law written with the catalyst concentrations included?

At 1:35, why is IO- the intermediate and not I? Vice Versa for the Catalyst.
