Benzene and toluene form nearly ideal solutions. At the vapour pressure of benzene is 75 torr and that of toluene is 22 torr. The partial vapour pressure of benzene a
for a solution containing 78 g of benzene and 46 g of toluene in torr is
As we learnt in
Rault's Law -
The total vapour pressure of binary mixture of miscible liquids be having ideally is given by
Where and
are mole fraction of A and B in liquid phase.
- wherein
and
are vapour pressures of pure liquids.
