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.
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; a catalyst only favors a chemical reaction, the reaction rate and yield.
The catalyst is not a reactant in a chemical reaction but contribute to the success of this reaction.

No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the 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 reactant that binds to a catalyst is known as a substrate. Substrates bind to the active site of the catalyst, where the chemical reaction takes place. This binding lowers the activation energy required for the reaction to occur.
Either an energy source to start the reaction or a catalyst.
a product
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
