Which solution will show the maximum vapour pressure at $300 \ K$?

Assertion $:-$ Vapour pressure of a liquid increases on increasing surface area.
Reason $:-$ Rate of vaporisation of a liquid is directly proportional to surface area.

$12 \ g$ of a nonvolatile solute dissolved in $108 \ g$ of water produces the relative lowering of vapour pressure of $0.1$. The molecular mass of the solute is

At $298 \ K$,if the vapour pressure of pure liquids toluene,benzene,chloroform and dichloromethane are $60, 160, 200$ and $415 \ torr$ respectively,then which liquid has the highest boiling point?

For two volatile liquids $A$ and $B$,if the vapour pressure ratio of $P_{A}^{0} : P_{B}^{0} = 1 : 2$ and the mole fraction ratio in the liquid phase is $X_{A} : X_{B} = 1 : 2$,then find the mole fraction of component $A$ in the vapour state $(Y_{A})$?

State Raoult's law for a solution containing a non-volatile solute and a volatile solvent and explain it.
