WebbΔG p is the Gibbs free energy of ATP synthesis: ADP + Pi → ATP also called phosphorylation potential. The H+ / ATP ratio values in the table above can be calculated by comparison of Δp and ΔG p, for example: H+ / ATP = 66 kJ·mol-1 / (200 mV / 10.4 kJ·mol-1/mV) = 66 / 19.2 = 3.4 (mitochondrion) WebbWhen both temperature and pressure are held constant, and the number of particles is expressed in moles, the chemical potential is the partial molar Gibbs free energy.

Webb11 apr. 2024 · Gibbs free energy changes for HERs and OERs. The thermodynamic feasibility of HER and OER can be examined by the Gibbs free energy ΔG as follows [64], [65], [66] (3) Δ G = Δ E + Δ E zpe-T Δ S. Where Δ E is the adsorption energy of a given group, Δ E zpe and T Δ S denote the zero-point energy WebbThe sign convention is the same as that for enthalpy, where a negative Gibbs free energy denotes energy released from the reaction. For the reaction of hydrogen with oxygen, this is written as: [7] [8] Where “G f ” represents the Gibbs free energy of formation. Gibbs free energy is affected by temperature and pressure as noted below: [9]
