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