Catalysts

Postby Erik Buetow 1F » Sat Mar 14, 2020 8:08 pm

Will a catalyst always show up first in the reactants side and then on the product side in a reaction mechanism? In other words, will we be able to tell that it is a catalyst because it is the opposite of how an intermediate works?

Exactly! The catalyst will have "disappeared" from the final reaction equation because it has been cancelled out (since it's in the reactant side of the first equation) and the product side of another equation

I believe so, yes.

I believe so, also in a reaction I think it can sometimes be represented on the arrow. It isn't necessarily the opposite of a intermediate, an intermediate is created and consumed. The catalyst is just a substance or molecule that a reaction takes place on. It isn't used up in the reaction.

A catalyst is not used up in the reaction, which means that it will appear first on the reactant side of one step of the reaction and then appear again as a product in another step of the reaction. However, the catalysts will not appear in the overall reaction.
