NEET Chemistry Raoult's Law MCQ Question
What happens to the vapor pressure of a solvent when a non-volatile solute is added, according to Raoult's law?
The vapor pressure decreases.
The vapor pressure increases.
The vapor pressure remains the same.
The vapor pressure fluctuates.
Correct Answer
Detailed Explanation
According to Raoult's law, the addition of a non-volatile solute to a solvent decreases the solvent's vapor pressure, making it equal to that of the pure solid solvent at a lower temperature.
