CHEM1405 2012-J-2 June 2012 • What is the ground state electron
... ΔG = -(8.314 J K-1 mol-1) × ((25 + 273) K) × 1.8 × 10-16 = +89 kJ mol–1 Answer: +89 kJ mol-1 Why is ΔG not equal to ΔH for this reaction? By definition, ΔG = ΔH – TΔS. As the entropy change for the reaction and the temperature are not zero, so ΔG ≠ ΔH. The pH of pure water is 6.81 at 37 °C. Is water ...
