NEET Chemistry Types of Solutions MCQ Question
If a non-volatile solute is added to a solvent, which of the following statements correctly describes the effect on the vapour pressure of the solution?
The vapour pressure of the solution is lower than that of the pure solvent.
The vapour pressure of the solution is higher than that of the pure solvent.
The vapour pressure of the solution remains the same as that of the pure solvent.
The vapour pressure of the solution depends solely on the temperature.
Correct Answer
Detailed Explanation
According to Raoult's Law, the addition of a non-volatile solute decreases the vapour pressure of the solvent in the solution compared to the pure solvent.
