NEET Chemistry Raoult's Law MCQ Question
Which of the following statements about ideal solutions, according to Raoult's Law, is true?
The enthalpy of mixing of pure components is zero.
The volume of mixing is always positive.
Ideal solutions do not obey Raoult's Law at all concentrations.
The vapor pressure of the solution is independent of the mole fraction of solvent.
Correct Answer
Detailed Explanation
Ideal solutions have the property that the enthalpy of mixing of the pure components to form the solution is zero, indicating no heat is absorbed or evolved during mixing, as stated in the NCERT context.
