Q. Consider a binary mixture of volatile liquids. If at $X_{A}=0.2$ , the vapour pressure of solution is $580torr$ , then the mixture could be $\left(P_{A}^{^\circ } = 200 torr , P_{B}^{^\circ } = 600 torr\right)$

Solution:

$P_{\left(ideal\right)}=0.2\times 200+0.8\times 600$
$=520torr < P\left(obs\right)$
Solution showing positive deviation.
