WebMay 10, 2024 · Chemical thermodynamics describes the change in enthalpy (∆H) and entropy ( ∆S) during a chemical reaction or change of state. The process will only be possible if the enthalpy and entropy changes combine to give a negative value for the change in free energy ( ∆G ), where ∆G = ∆H – T∆S. The formation of bonds is … WebProblem : Given that the free energy of formation of liquid water is -237 kJ / mol, calculate the potential for the formation of hydrogen and oxygen from water. To solve this problem we must first calculate ΔG for the reaction, which is -2 ( -237 kJ / mol) = 474 kJ / mol. Knowing that ΔG = -nFE o and n = 4, we calculate the potential is -1.23 V.
