What does `Delta G = 0` represent ?

Explanation

To understand what \( \Delta G = 0 \) represents, we can break down the concept into a few steps:

### Step 1: Understand Gibbs Free Energy
Gibbs free energy (\( G \)) is a thermodynamic potential that helps predict the direction of chemical reactions and the equilibrium position. It combines the system's enthalpy and entropy to determine the maximum reversible work that can be performed at constant temperature and pressure.

### Step 2: The Gibbs Free Energy Change (\( \Delta G \))
The change in Gibbs free energy (\( \Delta G \)) for a process is defined as:
\[
