Calculadora de Constante de Equilíbrio — Formula
## Equilibrium Constant from ΔG°
### Formula
**K = e^(−ΔG° / RT)**
Equivalently: **ΔG° = −RT ln(K)**
Where:
- **K** = equilibrium constant
- **ΔG°** = standard Gibbs free energy change (J/mol)
- **R** = 8.314 J/(mol·K)
- **T** = temperature (K)
Large K (K >> 1) means products are favored. Small K (K << 1) means reactants are favored.

Exemplo Resolvido
A reaction with ΔG° = -10 kJ/mol at 298 K.
- K = e^(-ΔG°/RT)
- K = e^(-(-10000)/(8.314 × 298))
- K = e^(10000/2477.6)
- K = e^(4.036)
- K = 56.6
