14. (Enthalpy and entropy of reaction from AH°; and S°) Given the following reaction
4HCI(g) + O2(g) → 2CI2(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), H2O(g) (188.7)
a. Determine AH°rn (in kJ/mol) and ASºxn (in J/mol·K) for the reaction below at 25°C
using the given AH°t and S° 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.
