Write the equation showing the relationship between standard free energy and standard cell potential.

Explanation

To derive the equation showing the relationship between standard free energy (ΔG°) and standard cell potential (E°cell), we can follow these steps:

### Step 1: Understand the Definitions
- **Standard Free Energy Change (ΔG°)**: This is the change in Gibbs free energy when a reaction occurs under standard conditions (1 bar pressure, 1 M concentration, and a specified temperature, usually 298 K).
- **Standard Cell Potential (E°cell)**: This is the voltage or electric potential difference of an electrochemical cell under standard conditions.

### Step 2: Write the Fundamental Relationship
The relationship between standard free energy change and standard cell potential is given by the equation:
