What is the difference between the catalyst and intermediate of the reaction?

A catalyst is used up and regenerated. An intermediate is formed and used up.

to add to your question, how can you tell which substance is a catalyst versus an intermediate when given a series of steps?

A catalyst can be an intermediate in an equation, but not all intermediates are catalysts. I believe to be able to tell if it is a catalyst you would have to be given that it is a catalyst or that the activation energy was lowered.

I believe it depends on the order in which the steps occur. For instance, a catalyst would be a reactant in a prior step and a product in a subsequent step, whereas an intermediate would be a product in a prior step and a reactant in a subsequent step.

In a series of reactions, you will always start with the catalyst as a reactant. In contrast, an intermediate is first introduced as a product because an intermediate is formed then used.

Catalyst is there in the beginning of reaction and is then recreated later on. An intermediate is created and used up during the reaction.

A catalyst is added to the reaction to make it faster, it is part of the reactants but then is regenerated. An intermediate is formed in the reaction and then used up, it does not need to be specifically added.

Adding on to this, if a molecule is cancelled out in step 1 on the reactants side of the equation when you are taking one of the approaches to solve the mechanism it is known as the catalyst, since it has been there from the beginning and is not consumed. You will be able to tell an intermediate, if it is produced in step 1 then it will be used up in step 2 on the reactants side.
