    When two liquids A and B form an ideal solution, then

    A) the Gibbs free energy is zero

    B) the entropy of mixing is zero

    C) the Gibbs free energy and entropy of mixing both are zero

    D) the enthalpy of mixing is zero

    Correct Answer: B

    Solution :

    [b]
    For an ideal solution, \[\Delta H=0,\,\,\Delta V=0.\]
    As force of attraction between \[AA\] and \[BB\]  molecules is equal to \[AB\] molecules.
