Calcolatore Tempo di Elettrolisi — Formula
## Arrhenius Equation
### Formula
**k = A × e^(−Ea / RT)**
Where:
- **k** = rate constant
- **A** = pre-exponential (frequency) factor
- **Ea** = activation energy (J/mol)
- **R** = 8.314 J/(mol·K)
- **T** = temperature (K)
The rate constant increases exponentially with temperature and decreases with higher activation energy.

Esempio Risolto
A = 1 × 10¹⁰, Ea = 50,000 J/mol, T = 298 K.
- k = A × e^(-Ea/RT)
- k = 1×10¹⁰ × e^(-50000/(8.314×298))
- k = 1×10¹⁰ × e^(-20.18)
- k = 1×10¹⁰ × 1.71×10⁻⁹
- k = 17.1
