WebApr 11, 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 difference and entropy, … WebGibbs Energy as a Function of Temperature If heat capacities are know from 0 K we could determine both enthalpy and entropy by integration: S ( T) = S ( 0) + ∫ 0 T C p T d T H ( T) = H ( 0) + ∫ 0 T C p d T As we have seen we must be careful at phase transitions such as melting or vaporization.
