catalyst vs intermediate

Postby Emily Duggan 1F » Sun Mar 11, 2018 1:01 pm

how do we determine the difference between the two since they are on both sides of the equation when given the steps to a reaction mechanism and we have to write the overall reaction? Thanks!

If it is serving as a reactant in the first step and then being produced in the second step then it is a catalyst. On the other hand, an intermediate must first be formed by one of the steps and then used up in later steps.

A catalyst will appear in both the reactants and products since it is not consumed during a reaction. On the other hand, an intermediate does not appear in the reactants or products because the intermediate is produced and consumed during the course of a reaction.
