Explain the state of a reaction when `DeltaG =0`.

Explanation

To explain the state of a reaction when ΔG = 0, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding ΔG**:
- ΔG represents the change in Gibbs free energy of a system. It is a thermodynamic potential that measures the maximum reversible work that can be performed by a thermodynamic system at constant temperature and pressure.

2. **Condition for ΔG = 0**:
...
