A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.

∙ 15y agoSubstrate and catalyst will both partake in a chemical reaction, but at the end of that reaction the substrate will be converted to a product which is structurally different to the substrate, while the catlyst is not structurally altered and will be able to catalyse more reactions with substrate.

What is a reactant that binds to a catalyst?
substrate
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
Are substrate and reactant the same or different?
Actually a substrate is a reactant. It undergoes a chemical reaction to yield a product. The difference is that a catalyst acts upon it to increment the rate of the reaction (by reducing the activation energy required).
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is a catalyst consumed by the reaction?
The terms reactant and reagent are often used interchangeably-however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction, are usually not called reactants. Similarly, catalysts are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates. So, it will be literally wrong to call catalyst a reagent.
Which does a catalyst not change?
Catalyst is not a reactant.
Why is a catalyst not a product or a reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Why is a catalyst not a product or reactant of a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
Is water a reactant or a catalyst in the chemical process of photosynthesis?
A catalyst
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
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 is a reactant that binds to a catalyst?
substrate
What is the difference between a reaction and products of a chemical reaction?
reactant + reactant = product
When hydrogen burns what is oxygenated role?
Oxygen acts as a reactant.
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
Is catalyst consumed by the reaction?
No. If something is consumer, then it is a reactant.
Is sodium hydroxide a reactant?
If NaOH is totally used up in the reaction process, it is a reactant; If not it's a catalyst.
