... Show that this reaction is spontaneous at 25 C. Using G° = H° - TS°, G° = (-198.4×103 J mol-1) – ((25+273) K) ×(-187.9 J mol-1) = -142400 J mol-1 = -142.4 kJ mol-1 As G° < 0, the reaction is spontaneous. If the volume of the reaction system is increased at 25 C, in which direction will the re ...
