A) \[\Delta {{G}^{o}}=-400\,\,kJ\,\,mo{{l}^{-1}}\]
B) \[\Delta {{H}^{o}}=200\,\,kJ\,\,mo{{l}^{-1}},\,\,\,\Delta {{S}^{o}}=-4\,\,J{{K}^{-1}}mo{{l}^{-1}}\]
C) \[\Delta {{H}^{o}}=-200\,kJ\,mo{{l}^{-1}},\,\,\Delta {{S}^{o}}=4\,J{{K}^{-1}}mo{{l}^{-1}}\]
D) \[\Delta {{H}^{o}}=200\,J\,mo{{l}^{-1}},\,\,\Delta {{S}^{o}}=40\,J{{K}^{-1}}mo{{l}^{-1}}\]
Correct Answer: A
Solution :
When \[\Delta H=+ve\] and \[\Delta S=-ve\] than the reaction is non-spontaneous.
