    If the vapour pressure of pure solvent is \[{{P}_{0}}\] and the vapour pressure of dilute solution of non-volatile solute is P, then the lowering in vapour pressure is :

    A)  \[+ve\]                               

    B)  \[-ve\]

    C)  \[P/{{P}_{0}}\]                

    D)  \[{{P}_{0}}/P\]

    Correct Answer: A

    Solution :

                    Lowering in vapour pressure is always positive since the vapour pressure of pure solvent is always greater than that of dilute solution containing non-volatile solute.
