    Lattice and hydration energies of \[NaCl\] are \[+777.8\text{ }kJ\text{ }mo{{l}^{-1}}\]and \[-774.1\text{ }kJ\text{ }mo{{l}^{-1}}\] respectively. Heat of solution of \[NaCl\] will be:

    A)  \[1551.9\text{ }kJ\text{ }mo{{l}^{-1}}\]   

    B)  \[-1551.9\text{ }kJ\text{ }mo{{l}^{-1}}\]

    C)  \[-37\text{ }kJ\text{ }mo{{l}^{-1}}\]

    D)  \[+3.7\text{ }kJ\text{ }mo{{l}^{-1}}\]

    Correct Answer: D

    Solution :

    Heat of solution = hydration of energy + lattice energy Heat of solution \[=-774.1+777.8\]                                 \[=+3.7\,kJ\,mo{{l}^{-1}}\]
