Question

Catalysts increase the rate of a reaction by

Answer 1

Answer:

Decreasing the activation energy of the reaction.

Explanation:

Catalyst may be defined as the substance that increase the rate of a bio chemical reaction. The catalyst does not change the equilibrium of the reaction.

The catalyst increase the rate of a chemical reaction by decreasing the activation energy of the reaction. The activation energy is the minimum amount of energy required for the conversion of reactant into product. The catalyst increases the effective collision between the molecules and decreases the activation energy. Hence, increases the rate of a reaction.

Answer 2

Catalysts increases the rate of a reaction by lowering the need for a larger reaction. Basically, the more reactions that are created, the faster the rate of the reactions will become. An example of this is Amylase in our saliva.
