    Which of the following plots represents the behaviour of an ideal binary liquid solution?

    A)  Plot of \[{{p}_{total}}\,\,vs\,\,{{Y}_{A}}\] (mole-fraction of A in vapour phase) is linear

    B)  Plot of \[{{p}_{total}}\,\,vs\,\,{{Y}_{B}}\]

    C)  Plot of \[1/{{p}_{total}}\,\,vs\,\,{{Y}_{A}}\]

    D)  Plot of \[1/{{p}_{total}}\,\,vs\,\,{{Y}_{B}}\] is non-linear

    Correct Answer: C

    Solution :

    \[{{Y}_{A}}=\frac{p_{A}^{{}^\circ }{{X}_{A}}}{{{p}_{total}}}\] Graph of \[{{Y}_{A}}\,vs\,\,\frac{1}{{{p}_{total}}}\,\,is\,\,linear\]
