______ states that for a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in solution.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Raoult’s law.
- Raoult's law states that the vapor pressure of a solvent above a solution is equal to the vapor pressure of the pure solvent at the same temperature scaled by the mole fraction of the solvent.
- This observation depends on two variables:
(i)the mole fraction of the amount of dissolved solute present and
(ii) the original vapor pressure (pure solvent).
