Explanation:
Freezing Point Depression:
- Freezing point depression refers to the phenomenon where the freezing point of a solvent is lowered when a non-volatile solute is added to it.
- This occurs because the presence of solute particles disrupts the regular arrangement of solvent molecules, making it more difficult for the solvent to form a solid lattice structure.
Vapour Pressure:
- Vapour pressure is the pressure exerted by a vapor when it is in equilibrium with its liquid phase.
- In a solution, the presence of solute particles affects the vapor pressure of the solvent.
- When a solute is added to a solvent, the vapor pressure of the solution is lower than that of the pure solvent.
- This is because the solute particles occupy some of the surface area of the solution, reducing the number of solvent molecules available to evaporate and thus lowering the vapor pressure.
Conclusion:
- In the depression of freezing point experiment, the vapor pressure of the solution is less than that of the pure solvent.
- This is due to the presence of solute particles in the solution, which reduces the number of solvent molecules available to evaporate and hence lowers the vapor pressure.
- Therefore, the correct answer to the question is option 'b' - "The vapor pressure of the solution is less than that of the pure solvent."
