How is free energy change related to equilibrium constant for the reaction?

Explanation

To understand how free energy change is related to the equilibrium constant for a reaction, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Free Energy Change (ΔG)**:
- The change in free energy (ΔG) for a reaction indicates the spontaneity of the reaction. If ΔG is negative, the reaction is spontaneous; if positive, it is non-spontaneous.

2. **Relation to Cell Potential (E)**:
