    Which of the following is not true for positive deviations?

    A) The A—B interactions in solution are weaker than the \[A-A\]and \[B-B\]interactions.

    B) \[{{P}_{A}}<P_{A}^{{}^\circ }{{x}_{A}}\] and \[{{P}_{B}}<P_{B}^{{}^\circ }{{x}_{B}}\]

    C) Carbon tetrachloride and chloroform mixture is an example of positive deviations.

    D) All of these.

    Correct Answer: B

    Solution :

    For positive deviations \[{{P}_{A}}>P_{A}^{{}^\circ }{{X}_{A}}\] and \[{{P}_{B}}>P_{B}^{{}^\circ }{{X}_{B}}\]
