{p_A}

and

{p_B}

are the vapour pressure of pure liquid components

A

and

B

respectively of an ideal binary solution. If

{\chi _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} + {\chi _A}\left( {{p_A} - {p_B}} \right)

Option D (

{p_B} + {\chi _A}\left( {{p_A} - {p_B}} \right)

) is correct because it represents the total pressure of an ideal binary solution according to Raoult's law.
