Question

The following is a graph plotted between the vapour pressure of two volatile liquids against their respective mole fractions.

Which of the following options are correct?

• A. When $x_A=1$ and $x_B=0$ then $p=p_A^{\circ }$
• B. When $x_B=1$ and $x_A=0$ then $p=p_B^{\circ }$
• C. When $x_A=1$ and $x_B=0$ then $p=p_B^{\circ }$
• D. When $x_B=1$ and $x_A=0$ then $p=p_A^{\circ }$

Answer 1

Answer: (A), (B)

Correct answer is (a) When $x_A=1$ and $x_B=0$ then $p=p_A^{\circ }$ Correct answer is (b) When $x_B=1$ and $x_A=0$ then $p=p_B^{\circ }$
