If the activation energies of the forward and backward reactions of a reversible reaction are `E_(a)(f)` and `E_(a)(b)`, respectively. The `DeltaE` of the reaction is ………..

Explanation

To find the change in energy (ΔE) of a reversible reaction given the activation energies of the forward and backward reactions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Activation Energy**:
- Activation energy (Ea) is the minimum energy required for a reaction to occur. For a reversible reaction, we have two activation energies:
- \( E_a(f) \): Activation energy for the forward reaction.
- \( E_a(b) \): Activation energy for the backward reaction.
