A catalyst is something that speeds up the reaction by providing a more suitable environment for it to occur, but is itself not consumed in the reaction. The simplest answer would be that if it reacted, then by definition, it would be another reactant and no longer considered only a catalyst.
The reason the catalyst is not affected can vary, but it could be because it's already in a stable form, stable enough not to be affected with the reactants.

Why do catalyst allow the chemical reaction take place at 0 Celsius?
When reactants are joined by a catalyst, they no longer have to collide with much energy to react. Thus, with the catalyst present the reaction can proceed at very low temperatures.
How does adding a catalyst to reaction affect it?
Provided the catalyst is appropriate for the reaction, it will accelerate the reaction. In other words, the reaction will reach equilibrium between reactants and products faster than it would otherwise have done. The catalyst is unchanged, i.e. at the end of the reaction it is in the same chemical state that it was in at the start. In living systems, the catalysts are made by cells and are called enzymes.
What happens to catalyst in a reaction?
it is incorporated into the reactants
Which component is affected when a catalyst is added to a chemical reaction?
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.
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
Which of the following is not true of a catalyst?
A catalyst is a material which make possible a chemical reaction, improve the rate of reaction, increases the yield of the reaction; a catalyst doesn't react with reactants/products.

What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What are the reactants of a catalyst-assisted reaction?
Reactants are also known as substrates.
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.

What are the molecules that react with one another called?
Molecules that react with one another are called reactants.
Which component is affected when a catalyst is added to a chemical reaction?
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.
Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
