  • question_answer What is the entropy change (in \[J{{K}^{-1}}\text{ }mo{{l}^{-1}}\]) when one mole of ice is converted into water at \[{{0}^{o}}C\]? (The enthalpy change for the conversion of ice to liquid water is \[6.0\text{ }KJ\text{ }mo{{l}^{-1}}\] at \[{{0}^{o}}C\])

    A)  \[20.13\]                     

    B)  \[2.013\]

    C)  \[2.198\]                     

    D)  \[21.98\]

    Correct Answer: D

    Solution :

    \[\Delta S=\frac{\Delta {{H}_{f}}}{{{T}_{f}}}=\frac{6000J}{273K}=21.98J{{K}^{-1}}mo{{l}^{-1}}\]
