Chemistry - Liquid Solution Question with Solution | TestHub

(A) $P_A^0>P_B^0$ means $A$ is more volatile than $B$ and therefore $A$ will be richer in vapour phase. [or $YA=\mathrm{XA}\frac{{\mathrm{P}}_{\mathrm{A}}^0}{{\mathrm{P}}_{\mathrm{T}}}$

(B) For Azeotropes, composition of vapour phase and liquid phase is same

(C) For $P_A^0<P_B^0,<X_B<Y_B$ and $Y_B>Y_A$ for an equimolar ratio.

(D) For $P_A^0=P_B^0,X_A=Y_A$ for an equimolar ratio.
