Gibbs Free Energy Calculator (ΔG)
Compute the Gibbs free energy change of a reaction using enthalpy, temperature, and entropy.
Formula:
Gibbs Free Energy Change (ΔG):
ΔG = ΔH - T × ΔS / 1000
- ΔH: enthalpy change (kJ)
- T: temperature (K)
- ΔS: entropy change (J/K)
- ΔG < 0 : Reaction is spontaneous
- ΔG > 0 : Reaction is non-spontaneous
