Gibbs free energy
relates enthalpy, entropy and Gibbs free energy changes at constant temperature.
symbols, variables and units
ΔG,ΔH：J/mol；ΔS：J/(mol·K)；T：K。
applicable conditions and boundaries
The same temperature; constant temperature and pressure and only volume work, ΔG determines the spontaneous direction.
formula source code
The following is a copyable LaTeX expression.
\Delta G=\Delta H-T\Delta S
