WebThe energy associated with a chemical reaction that can be used to do work.The free energy of a system is the sum of its enthalpy (H) plus the product of the temperature (Kelvin) and the entropy (S) of the system. The Gibbs free energy is the maximum amount of non-expansion work that can be extracted from a thermodynamically closed system … WebNov 27, 2024 · Gibbs Free Energy and Spontaneity . The change in Gibbs free energy or the Gibbs function may be used to assess the spontaneity of a process. At constant temperature and pressure, the Gibbs equation is ΔG = ΔH - TΔS, in which ΔH is the change in enthalpy, ΔS is the change in entropy, and ΔG is the amount of free or available energy.
