$p_{1}^{0}$ is the vapour pressure of liquid $1, p_{2}^{0}$ is the vapour pressure of liquid 2 at th

Question

$p_{1}^{0}$ is the vapour pressure of liquid $1, p_{2}^{0}$ is the vapour pressure of liquid 2 at the same temperature and $\chi_{1}$ and $\chi_{2}$ are respectively their mole fractions. P is the total vapour pressure of the solution.Which of the following is incorrect?

Professor PC Thomas Classes · Answer

As $p_{1}^{0}>p_{2}^{0}$, addition of more liquid 2 causes a decrease in P from $p_{1}^{0}$ to $p_{2}^{0}$ along AB.
