### Catalysts

If given the reaction mechanisms, how can you identify if a catalyst was involved?

Rule of thumb for me is that they show up as a reactant first then a product. An intermediate will show up as a product first then a reactant

Dr. Lavelle also states during lecture that catalysts are not formed, but used up. Therefore, a reactant would be a good example of this since it is not the product of the reaction.

A catalyst is first a reactant and is used up, then is a product and is formed.
