Question

Liquids A and B form an ideal solution. The plot of 1/X_A (Y-axis) versus 1/Y_A (X-axis) (where X_A and Y_A are the mole fractions of A in liquid and vapour phases at equilibrium, respectively) is linear whose slope and intercept, respectively, are given as

Prashant Kotian · Accepted Answer

Correct answer: B. From Raoult's law: 1/Y_A = (P_B°/P_A°) × (1/X_A) + (P_A° − P_B°)/P_A°. Slope = P_B°/P_A°, intercept = (P_A° − P_B°)/P_A°.
