Use the following information: [[[[2H2(g) + O2(g) → 2H2O(l) ∆H = −572 kJ mol−1]]]] [[[[2H2(g) + O2(g) → 2H2O(g) ∆H = −484 kJ mol−1]]]] to calculate the enthalpy change for the process: H2O(g) → H2O(l)
Calculate ΔG (in kJ/mol) of the reaction of molecular oxygen and carbon monoxide to produce carbon dioxide. The reaction occurs at 25°C. ΔH = -566 kJ/mol, ΔS = -173 J/K. Based on the result, determine the spontaneity of the reaction.
