A reversible reaction has `DeltaG^(@)` negative for forward reaction ? What will be sign of `DeltaG^(@)` for backwork reaction ?

Explanation

To determine the sign of ΔG° for the backward reaction when ΔG° for the forward reaction is negative, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of ΔG°**:
- ΔG° (Gibbs free energy change) indicates the spontaneity of a reaction. A negative ΔG° for the forward reaction means that the reaction proceeds spontaneously in the forward direction.

2. **Identify the Forward and Backward Reactions**:
...
