In steam distillation of toluene , the pressure of toluene in vapour is

A

equal to the pressure of barometer

B

less than the pressure of barometer

C

equal to vapour pressure of toluene in simple distillation

D

more than vapour pressure of toluene in simple distillation

Text Solution

Verified by Experts

The correct Answer is:
B
In steam distillation of toluene , the pressure of toluene in vapour is less than pressure of barometer , because it is carried out when a solid or liquid is insoluble in water and is volatile with steam but the impurities are non-volatile.

At 334K the vapour pressure of benzene (C_(6)H_(6)) is 0.526 atm and that of toluene (C_(7)H_(8)) is 0.188 atm. In a solution containing 0.500 mole of benzene and 0.500 mole of toluene , what is the vapour pressure of toluene for above solution at 334K ?

Toluene may be prepared by :

The mole fraction of toluene in vapour phase which is in equlibrium with a solution of benzene and toluene having a mole fraction of toluene 0.500 is (vapour pressure of pure benzene and pure toluene are 119 torr and 37.0 torr respectively at the same temperature).

A solution at 20^(@)C is composed of 1.5 mol of benzene and 3.5 mol of toluene. If the vapour pressure of pure benzene and pure toluene at this temperature are 74.7 torr and 22.3 torr, respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively:

Steam distillation in principle is comparable to distillation under reduced pressure. Do you agree to it ?
