Question
CBSEENCH12005800

State Raoult’s layer for a binary solution containing volatile components.

Solution

Answer:

Raoult's law states that for a solution of volatile liquid, the partial vapour pressure of each component in the solution is directly proportional to its mole fraction.
Thus if there is solution of two liquid component 1and 2, then
for component 1,
      
      p1   x1and p1 = p10x1For component 2,p2 = p20x2

Where 
p1p2 = partial vapour pressure of two volatile component in solution 1 and 2 
p10 p 20 = vapour pressure of pure component1 and 2
x1x2 = mole fraction of component.
