Chemistry-Raoult's Law
NEET Chemistry Raoult's Law MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about solutions and their properties is correct?
A
The elevation of boiling point depends only on the nature of the solute.
B
Raoult's law applies to ideal solutions where the enthalpy of mixing is zero.
C
Henry's law states that the vapor pressure is inversely proportional to the mole fraction.
D
A solution's boiling point is always lower than that of the pure solvent.
Correct Answer
Option B
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.
