Select correct statement:
  • a)
    Solution has more molecular randomness than a pure solvent has, the entropy change between solution and solid is larger than the entropy change between pure solvent and solid.
  • b)
    Heat of fusion of solution and solvent are similar since similar forces of intermolecular forces are involved.
  • c)
    Sugar containing solution freezes at a lower temperature than pure water.
  • d)
    All are correct statements.
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Select correct statement:a)Solution has more molecular randomness than...
A) Entropy of solution 
>
 Entropy of pure solvent

(ΔS)solution-solid>(ΔS)solvent-solid

In solution, number of particle is greater so solution have greater entropy.

(B) Only solvent involved in solid-liquid equilibrium.

D is the correct answer

Select correct statement:a)Solution has more molecular randomness than...
Explanation:

  • Molecular randomness and entropy change: When a solute is dissolved in a solvent to form a solution, the molecular randomness increases because the solute molecules mix randomly with the solvent molecules. This makes the entropy change between solution and solid larger than the entropy change between pure solvent and solid.

  • Heat of fusion: The heat of fusion of a solution is not necessarily similar to that of the solvent because the forces of intermolecular attraction between solute and solvent molecules may differ from those between solvent molecules.

  • Freezing point depression: When a solute is dissolved in a solvent, the freezing point of the resulting solution is lower than that of the pure solvent. This is because the solute molecules interfere with the formation of the solvent crystal lattice, making it more difficult for the solvent molecules to arrange themselves in an ordered manner and freeze.

  • Conclusion: Therefore, all the given statements are correct.
