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
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.

a product
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
reactant + reactant = product
A catalyst is neither a product nor a reactant; it is a substance that accelerates a chemical reaction without being consumed in the process. It facilitates the reaction by lowering the activation energy required, allowing reactants to convert to products more efficiently. After the reaction, the catalyst remains unchanged and can be used again.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
In a chemical reaction the limiting reactant is the reactant that there is the least of in the reaction; it determines the amount of product formed. In a chemical reaction it is the reactant that gets completely "used up"
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.
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
