14. (Enthalpy and entropy of reaction from AH°; and S°) Given the following reaction 4HCI(g) + O2(g) → 2C12(g) + 2H2O(g) AH°, kJ/mol: HCI(g) (-92.31), H2O(g) (-241.8) S°, J/mol·-K: HCI(g) (186.8), O2(g) (205), Cl2(g) (223.0), H20(g) (188.7) a. Determine AH°ron (in kJ/mol) and AS°xn (in J/mol-K) for the reaction below at 25°C using the given AH°; and Sº values. b. Determine AG° (in kJ/mol) at 25°C and 1 atm and identify whether the reaction is spontaneous on the forward direction, spontaneous on the backward direction, or in equilibrium. c. Is the forward reaction spontaneous at lower temperatures, spontaneous at higher temperatures, spontaneous at all temperatures, or nonspontaneous at all temperatures? Explain briefly.
