A) \[9.77\,\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]
B) \[10.73\,\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]
C) \[2930\,\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]
D) \[108.5\,\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]
Correct Answer: A
Solution :
\[\Delta {{S}_{f}}=\frac{\Delta {{H}_{f}}}{{{T}_{f}}}\] \[\Delta {{S}_{f}}=\frac{2930\,J\,mo{{l}^{-1}}}{300\,K}=9.77\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]
