Thermochemistry & Thermodynamics

Gibbs Free Energy

The thermodynamic potential whose change determines whether a process is spontaneous at constant temperature and pressure.

ΔG = ΔH − TΔS kJ/mol Thermochemistry & Thermodynamics

Gibbs–Helmholtz Equation

The relation showing how the Gibbs free energy of a system varies with temperature.

(∂(ΔG/T)/∂T)_p = −ΔH/T² kJ/mol
