No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.
Reactants: the initial substances in a chemical reaction Products: the final substances in a chemical reaction Catalyst: a stimulator of a chemical reaction, not directly involved in the reaction, remain unchanged
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.

a Catalyst
catalyst
A catalyst is not included as a product in the chemical equation because it is not consumed in the reaction. Instead, it speeds up the reaction without being permanently altered itself. It remains unchanged at the end of the reaction and can be used in multiple reaction cycles.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
