Q2ChemistryUnit 5: Solutions

The vapour prerssure of pure liquids

A

and B are 400 and

600 m m H g

respectively at

298 K .

On mixing the two liquids, the sum of their initial volumes is equal to the volume of the final mixture. The mole fraction of liquids B is 0.5 in the mixture. The vapour pressure of the final solution,the mole fraction of components

A

and

B

in vapour phase, respectively are:

Q3ChemistryUnit 5: Solutions

The incorrect statement is :

Q4ChemistryUnit 5: Solutions

Two liquids

X

and

Y

form an ideal solution at

300 K

, the vapour pressure of the solution containing 1 mole of

X

and 3 moles of

Y

is 550 mm Hg. At the same temperature, if 1 mole of

Y

is further added to this solution, the vapour pressure of the solution increases by 10 mm

H g .

Vapour pressure (in

\mathrm{mm}

Hg ) of

\boldsymbol{X}

and

\boldsymbol{Y}

in their pure states will be respectively:
