    For an ideal solution with \[P_{A}^{o}>P_{B}^{o}\], which of the following is true?

    A) \[{{({{x}_{A}})}_{liquid}}={{({{x}_{A}})}_{vapour}}\]

    B) \[{{({{x}_{A}})}_{liquid}}>{{({{x}_{A}})}_{vapour}}\]

    C) \[{{({{x}_{A}})}_{liquid}}<{{({{x}_{A}})}_{vapour}}\]

    D) \[{{({{x}_{A}})}_{liquid}}\]and\[{{({{x}_{A}})}_{vapour}}\]do not bear any  relationship with each other.

    Correct Answer: C

    Solution :

    [c] : The vapour contains more of the volatile component [a] to that present in the solution, i.e., \[{{({{x}_{A}})}_{liquid}}<{{({{x}_{A}})}_{vapour}}.\]
