Question

Liquid **A** and **B** form an ideal solution. The vapour pressure of pure liquids **A** and **B** are **$$350 \, 	ext{mm Hg}$$** and **$$750 \, 	ext{mm Hg}$$** respectively at the same temperature. If $$x_A$$ and $$x_B$$ are the mole fraction of **A** and **B** in solution while $$y_A$$ and $$y_B$$ are the mole fraction of **A** and **B** in vapour phase then :

Accepted Answer

C. $$\frac{x_A}{x_B} > \frac{y_A}{y_B}$$

Answer

A. $$\frac{x_A}{x_B} < \frac{y_A}{y_B}$$

Answer

B. $$\frac{x_A}{x_B} = \frac{y_A}{y_B}$$

Answer

D. $$(x_A - y_A) < (x_B - y_B)$$
