WebSep 1, 2024 · The standard Gibbs free energy change, ΔG°, indicates the thermodynamic favorability of a physical or chemical process.When ΔG° < 0, the process is thermodynamically favored.For a given process, the value of ΔG° can be calculated directly from the values of ΔH° and ΔS° using the following equation: ΔG° = ΔH° - TΔS°. Created … WebJun 8, 2016 · $$\Delta G = \Delta H - T \Delta S$$ So even if entropy and enthalpy were temperature-independent (again, they are not), $\Delta G$ would still depend significantly on temperature. Oddly enough, a rigorous treatment of the temperature-dependence of $\Delta G$ gives the result that you would get from differentiating the defining equation with ...
