How is `DeltaG^(@)` related to equilibrium constant?

Explanation

To understand how the change in Gibbs free energy (ΔG°) is related to the equilibrium constant (K_eq) of a reaction, we can derive the relationship step by step.

### Step-by-Step Solution:

1. **Understanding ΔG°**:
The change in Gibbs free energy at standard conditions (ΔG°) is a measure of the maximum reversible work that can be performed by a thermodynamic system at constant temperature and pressure.

2. **Using the Nernst Equation**:
...
