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.
