Catalysts generally affect a chemical reaction by increasing its reaction rate by lowering the activation energy of the reaction. Catalysts are widely used to enhance the rate of any chemical reaction without changing the product.
What are Catalysts?
A Catalyst may be defined as a substance that overall changes the rate of reaction without being consumed in a reaction.
The catalysts are widely used when the rate of a given chemical reaction is not considerably altered by changing various conditions such as temperature, concentration, pH, etc., of the reactants.
Such new substances are brought which are not directly involved in the reaction and are mixed. And they finally made alterations in the given chemical reaction. Such new substances are known as a catalyst.
The process by which a catalyst changes the reaction rate without being involved in it is known as catalysis.
Therefore, catalysts generally affect a chemical reaction by increasing its reaction rate. Catalysts are widely used to enhance the rate of any chemical reaction without changing the product.
