Question

what is the effect of using catalyst in a reaction on

(i) activation energy

(ii) gibbs energy of a reaction

Answer 1

Activation energy is the minimum amount of energy required to start a reaction.Generally, without a catalyst the activation energy is very high.Thus a catalyst is used to reduce the activation energy required without which a large amount of external energy needs to be supplied for the reaction to take place.

On the other hand, the Gibbs free energy of the reactants and the products does not change with the presence of a catalyst.

Hope this helps

Answer 2

Hey !!

1) Activation energy

→ Decreases

2) Gibbs Energy

→ No effect

Hope it helps you !!
