Determining Catalysts from Diagrams (7E.5)

Postby Searra Harding 4I » Thu Mar 14, 2019 1:27 am

In 7E.5 we are given the diagrams for each step. How do we know which molecule is the catalyst for the reaction? Is it the intermediate or reactant in the first step?

A catalyst is a molecule that is used up in a reaction and then re-created. I usually use this fact to help differentiate the catalyst from the intermediate (which is created then consumed by the rxn).

The catalyst is used up first then later recreated while an intermediate is first created/produced then used up and not in the final product and this is how you would tell the difference I think.

A catalyst is used up in the beginning of the reaction and then recreated.
An intermediate is created and then used up.
