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 $p=p_{B}^{\circ}$
