## Key Concepts

### Fundamental Equations

**Nernst Equation**
```
E = E° - (RT/nF) ln(Q)
E = E° - (0.0592/n) log(Q) at 298K
```

**Butler-Volmer Equation**
```
i = i₀ [exp(-αfη) - exp((1-α)fη)]
```

### Electrochemical Techniques

```python
# Example: Cyclic voltammetry analysis
def cyclic_voltammetry(potential_range, scan_rate):
    """
    Simulate cyclic voltammogram.
    potential_range: E_start to E_reverse
    scan_rate: dE/dt (V/s)
    """
    # Peak current (Randles-Sevcik)
    ip = 2.69e5 * n**1.5 * A * D**0.5 * C * v**0.5
    return {'peak_current': ip, 'formal_potential': E_f}
```
