Question
State ‘Raoult’s Law’ for a solution of volatile liquids.
Expert Solution
Step 1
According to Raoult’s law a solvent’s partial vapour pressure in a solution (or mixture) is equal to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.
Mathematically, Raoult’s law equation is written as;
Where,
= vapour pressure of the solution
Χsolvent = mole fraction of the solvent
P0solvent = vapour pressure of the pure solvent
