Question

What is the result of using a catalyst in a chemical reaction?

Answer 1

Using a catalyst in a chemical reaction will result in increasing the reaction rate.

Explanation:

Using a catalyst in a chemical reaction will result in increasing the reaction rate and therefore, the reactants will be converted to products in a faster way relative to the absence of catalyst.

In chemical kinetics, the use of a catalyst will lead to a decrease in the activation energy (`E_a`) of the reaction.

The activation energy is the energy difference between the potential energy of the reactants and that of the transition state of the reaction ( see below ).
