With the help of Raoult's law show that total vapour pressure of a binary liquid solution varies linearly with the mole fraction of a component.

Benzoic acid completely dimerises in benzene. What will be the vapour pressure of a solution containing 61g of benzoic acid per 500g benzene when the vapour pressure of pure benzene at the temperature of experiment is 66.6 Torr?

The vapour pressures fo pure liquids A and B are 450 mm Hg and 700 mm Hg respectively at 350K. If the total vapour pressure of the mixture of the two liquids at 350K is 600mm Hg, Calculate the more fractions of the two components in the solution. Also, calcuate the partial pressures of the two components in the vapour phase.

Heptane and octane form an ideal solution. At 373 K, the vapour pressures of the two liquid components are 105.2 kPa and 46.8 kPa respectively. What will be the vapour pressure of a mixture of 26.0 g of heptane and 35 g of octane?

100 g of liquid A (molar mass 140 g mol^-1) was dissolved in 1000g of liquid B (molar mass 180 g mol^-1) .
