In what cases would the concentration of the catalyst be part of the rate law?

This is a post-laboratory question in my Inorganic Chemistry Class, and the only case that I was able to research from the internet, where the concentration of the catalyst could be part of the rate law, is when the product of the reaction itself acts as a catalyst (auto-catalysis).





Are there any other cases? Any help would be very much appreciated :). Thank you very much. :DIn what cases would the concentration of the catalyst be part of the rate law?
_____A catalyst is a substance that allows reactants to go to products more easily. Thus, they are involved in the rate-determining step, which may or may not resemble the uncatalyzed transition state.
