Web12 feb. 2024 · In thermodynamics, the change in Gibbs free energy, ΔG, is defined as: (6.2.3.3.1) Δ G = Δ H − T Δ S. where. ΔG = change in Gibbs free energy of the reaction. ΔH = change in enthalpy. ΔS = change in entropy. Δ G o is the change in Gibbs energy when the reaction happens at Standard State (1 atm, 298 K, pH 7). WebFor example, the bond energy of the carbon-hydrogen bond in a methane (CH 4) molecule is equal to the average of the bond dissociation energies of each individual carbon-hydrogen bond. It can be calculated as follows. CH 4 + BDE 1 → CH 3 + H CH 3 + BDE 2 → CH 2 + H CH 2 + BDE 3 → CH + H CH + BDE 4 → C + H
