(Q67) What is the entropy change (in J/K) in the universe (AS universe) that occurs when nitrogen and
oxygen gas combine to form dinitrogen monoxide gas at 25°C?
2 N₂ (g) + O₂ (g) --> 2 N₂O (g)
The enthalpy change for the reaction (AHrxn) is 163.2 kJ and the entropy change for the reaction
(ASrxn) is -148.4 J/K.
