What is the effect of adding a catalyst on
(a) Activation energy (Ea), and
(b) Gibbs energy (`DeltaG`) of a reaction?

Explanation

To answer the question regarding the effect of adding a catalyst on activation energy (Ea) and Gibbs energy (ΔG) of a reaction, we can break it down into two parts:

### Step-by-Step Solution:

**(a) Effect of Catalyst on Activation Energy (Ea):**

1. **Definition of Activation Energy (Ea):**
- Activation energy is the minimum energy required for reactant particles to overcome the energy barrier and form products.
