(a) Derive a relationship between relative lowering of vapour pressure

1.	(a) Derive a relationship between relative lowering of vapour pressure and mole fraction of thevolatile liquid. (b) (i) Benzoic acid completely dimerises in benzene. What will be vapour pressure of a solutioncontaining 61 g of benzoic acid per 500 g of benzene when the vapour pressure of purebenzene at the temperature of experiment is 66.6 torr ? (ii) What would have been the vapour pressure in the absence of dimerisation ? (iii) Derive a relationship between mole fraction and vapour pressure of a component of an ideal solution in the liquid phase and vapour phase.
Answer» SOLUTION :64.19 TORR
