Standard Free Energy
What is the standard free energy change, ##\triangle##G##^\circ##, for the following reaction at 298 K? Is the reaction spontaneous?
2 PCl##_3## (g) + O##_2## (g) ##\longrightarrow## 2 POCl##_3##, ##\triangle##H = – 620.6 kJ/mol
Values of standard molar entropy, S##_{f}^\circ## are as follows: 2 PCl##_3## (g), 311.8 J/K; O##_2## (g), 205.1 J/K; POCl##_3##, 222.4 J/K
