NEET Chemistry Raoult's Law MCQ Question
Which of the following statements about solutions and their properties is correct?
The elevation of boiling point depends only on the nature of the solute.
Raoult's law applies to ideal solutions where the enthalpy of mixing is zero.
Henry's law states that the vapor pressure is inversely proportional to the mole fraction.
A solution's boiling point is always lower than that of the pure solvent.
Correct Answer
Detailed Explanation
Raoult's law applies to ideal solutions, where the enthalpy of mixing is zero, meaning that no heat is absorbed or evolved during mixing. This is a key characteristic of ideal solutions as stated in the NCERT context.
