{P_A}

and

{P_B}

are the vapour pressures of pure liquid components

A

and

B

respectively of an ideal binary solution. If

{X_A}

represents the mole fraction of component

A

, the total pressure of the solution will be

View answer and explanation

Correct option: D

{P_B} + {X_A}\left( {{P_A} - {P_B}} \right)

Option D (

{P_B} + {X_A}\left( {{P_A} - {P_B}} \right)

) is correct because it correctly represents the total pressure of an ideal binary solution based on Raoult's law.

Consider the solution of ethanol. In it Assertion: Isotonic solutions don't show net phenomenon of osmosis.

Reason: Isotonic solutions have equal osmotic pressure at constant temperature. 0.2 molal aqueous solution of a monobasic acid is 60% ionised. If Kb for water is

0.52\,K\,kg\,mo{l^{ - 1}}

then the boiling point of the solution will be The vapour pressures of pure liquids
