A) \[11.73\,J{{K}^{-1}}mo{{l}^{-1}}\]
B) \[18.84\,J{{K}^{-1}}mo{{l}^{-1}}\]
C) \[21.97\,J{{K}^{-1}}mo{{l}^{-1}}\]
D) \[24.47\,J{{K}^{-1}}mo{{l}^{-1}}\]
Correct Answer: C
Solution :
Entropy change of fusion \[\Delta {{S}_{f}}=\frac{\Delta {{H}_{f}}}{T}\] \[\Delta {{H}_{f}}=60\times {{10}^{3}}J,\,mo{{l}^{-1}},T=273\,K\] \[\Delta {{S}_{f}}=\frac{60\times {{10}^{3}}}{273}\] \[=21.97\,J\,{{K}^{-1}}\,mo{{l}^{-1}}\]You need to login to perform this action.
