NEET Chemistry Van't Hoff Factor MCQ Question
Which of the following statements about colligative properties and solutions is correct?
Colligative properties depend on the nature of solute particles present in the solution.
The vapour pressure lowering of a solvent is directly proportional to the mole fraction of the solute.
Solutions that exhibit maximum boiling azeotropes have higher vapour pressures than their components.
Osmotic pressure is solely influenced by the temperature of the solution regardless of solute concentration.
Correct Answer
Detailed Explanation
The vapour pressure of the solvent is lowered by the presence of a non-volatile solute, and this lowering is governed by Raoult’s law, which states that the relative lowering of vapour pressure is equal to the mole fraction of the solute. Therefore, option B is correct.
