Problem

Vapour pressure of

\text{CH}_3\text{Cl}

and

\text{CH}_2\text{Cl}_2

are 540 mm Hg and 402 mm Hg respectively. 101 g of

\text{CH}_3\text{Cl}

and 85 g of

\text{CH}_2\text{Cl}_2

are mixed together. Determine: a. The pressure at which the solution starts boiling. b. Molar ratio of solute v/s solvent in vapour phase in equilibrium with solution.
