What does `Delta G = 0` represent ?

Explanation

To understand what \( \Delta G = 0 \) represents, we can break down the concept of Gibbs free energy and its implications in chemical reactions step by step.

### Step-by-Step Solution:

1. **Understanding Gibbs Free Energy (G)**:
- Gibbs free energy (G) is a thermodynamic potential that measures the maximum reversible work that can be performed by a thermodynamic system at constant temperature and pressure.
- The formula for Gibbs free energy is given by:
\[
