For a completely ideal binary liquid solution, which of the following mathematical plots strictly yi — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

While $P_{total} = P^0_A X_A + P^0_B X_B$ forms a straight line against $X_A$, it is a curve against $Y_A$. The strictly linear relationship involving the vapour phase mole fraction is given by Dalton-Raoult manipulation: $\frac{1}{P_{total}} = \frac{Y_A}{P^0_A} + \frac{Y_B}{P^0_B}$.
