Question

'At constant temperature and for a solution of volatile liquids, the partial vapour pressure of each component in the solution is directly proportional to its mole fraction'. This forms the statement of

Professor PC Thomas Classes · Answer

Raoult's law: The partial vapour pressure of a component in a mixture of volatile liquids is equal to the product of mole fraction of the component and vapour pressure of the pure component. $p_{1}=\chi_{1} p_{1}^{0}$ and $p_{2}=\chi_{2} p_{2}^{0} P_{total }=p_{1}+p_{2}($ Daltons law $)$
