Question

Identify the false statement: (A) The volume of a solution cannot be less than the sum of volumes of the pure solvent and solute used to prepare the solution (binary solution of two liquids) (B) At constant T and P , Δ G operatornamemix will be necessarily negative for an ideal solution (C) An ideal binary solution (pA0 ≠ pB0) cannot form an azeotropic mixture. (D) In binary solutions ideality is more of an exception rather than a rule.

(A) as in case of negative deviation.
(B)

Δ G_{mix}

is generally positive.
(C) Ideal mixture follows Raoult's law at all compositions, so can not form a constant boiling mixture.
(D) It is theoretically impossible to obtain an ideal solution.

At constant $T$ and $P, Δ G_{mix}$ will be necessarily negative for an ideal solution

An ideal binary solution $(p_{A}^{0} \neq = p_{B}^{0})$ cannot form an azeotropic mixture.
