    Unit of entropy is

    A)  \[J{{K}^{-1}}mo{{l}^{-1}}\]                         

    B)  \[J\,mo{{l}^{-1}}\]         

    C)         \[{{J}^{-1}}{{K}^{-1}}mo{{l}^{-1}}\]

    D)         \[JK\,mo{{l}^{-1}}\]

    Correct Answer: A

    Solution :

    \[\Delta S=\frac{q}{T}\] q = required heat per mol  T = constant absolute temperature. Unit of entropy is \[J{{K}^{-1}}mo{{l}^{-1}}\]
