    If a reaction involves only solids and liquids which of the following is true?

    A) \[\Delta H<\Delta E\]       

    B) \[\Delta H=\Delta E\]

    C) \[\Delta H>\Delta E\]       

    D) \[\Delta H=\Delta E+\Delta nRT\]

    Correct Answer: B

    Solution :

    \[\Delta H=\Delta E+P\Delta V\], for solid and liquid, \[\Delta V=0\] or \[\Delta H=\Delta E+\Delta nRT\], for solids and liquids \[\Delta n=0\]
