Q. Mixture of volatile components A and B has total vapour pressure (in torr)

$P=254-119X_{A}$

where, $X_{A}$ is mole fraction of A in mixture. Hence, $P_{A}^{o}$ and $P_{B}^{o}$ are (in torr)

Solution:

When $X_{A}=1,$

$P=P_{A}^{o}$

So $P_{A}^{o}=254-119=135torr$

When $X_{A}=0,$

$P=P_{B}^{o}$

So $P_{B}^{o}=254$ torr.
