How to calculate equilibrium constant from gibbs energy
This calculator finds an equilibrium constant from standard Gibbs free energy and temperature.
How the calculation works
K = e^(−ΔG°×1000 ÷ (8.314462618 × T)).
Example
ΔG° = −10 kJ/mol at 298K: e^(10,000÷(8.314×298)) ≈ 56.7.
Frequently asked questions
How is Result calculated?
Result = exp( − [Standard Gibbs energy] × 1000 ÷ (8.3145 × [Temperature])).
Is the Equilibrium Constant from Gibbs Energy Calculator free to use?
Yes — every calculator on Simple Calculator Tools is free, runs in your browser, and does not require an account.
