Two liquids "A" and "B" forming an ideal solution has a total vapour pressure of "900mm" Hg at `20^(@)C` The mole fraction of "A" in the liquid mixture is "0.5" .If the vapour pressure of pure "B" is twice that of pure "A" ,the partial pressure of "A" in the vapour phase is :

If P_(A) is the vapour pressure of a pure liquid A and the mole fraction of A in the mixture of two liquids A and B is x, the parial vapour pressure of A is:

Two liquids A and B are mixed to form an ideal solution. The totol vapour pressure of the solution is 800 mm Hg. Now the mole fractions of liquid A and B are interchanged and the total vapour pressure becomes 600 mm of Hg. Calculate the vapour pressure of A and B in pure form. (Given : p_(A)^(@)-p_(B)^(@)=100 )

Liquids A (p_(A)^(@)=360" mm Hg") and B(p_(B)^(@)=320" mm Hg") are mixed. If solution has vapour pressure 340 mm Hg, then mole fraction of B will be

Vapour pressure of a pure liquid does not depend upon

Two liquids, A and B form an ideal solution. At the specified temperature, the vapour pressure of pure A is 20 mm Hg while that of pure B is 75 mm Hg . If the vapour over the mixture consists of 50 mol percent A , what is the mole percent A in the liquid?

In a mixture of A and B having vapour pressure of pure A and B are 400 m Hg and 600 mm Hg respectively. Mole fraction of B in liquid phase is 0.5. Calculate total vapour pressure and mole fraction of A and B in vapour phase .

The vapour pressure of pure liquid A is 0.80 atm. On mixing a non-volatile B to A, its vapour pressure becomes 0.6 atm. The mole fraction of B in the solution is:

Mole fraction of component A in vapour phase is chi_(1) and that of component A in liquid mixture is chi_2 , then ( p_(A)^@ )= vapour pressure of pure A, p_(B)^@ = vapour pressure of pure B), the total vapour pressure of liquid mixture is

Mole fraction of component A in vapour phase is chi_(1) and that of component A in liquid mixture is chi_2 , then ( p_(A)^@ )= vapour pressure of pure A, p_(B)^@ = vapour pressure of pure B), the total vapour pressure of liquid mixture is

The vapour pressure of pure liquids A and B is 450 and 700mm Hg , respectively, at 350K. Find out the composition of the liquid mixture if the total vapour pressure is 600mm Hg . Also find the composition of the vapour phase.
