NEET Chemistry Raoult's Law MCQ Question
Consider a graph depicting the relationship between vapour pressure and mole fraction for a liquid-liquid solution that obeys Raoult's Law. Which of the following statements best describes the nature of the graph?
The graph is a straight line indicating an ideal solution with zero enthalpy of mixing.
The graph is a curve indicating a non-ideal solution with positive enthalpy of mixing.
The graph is a straight line indicating a non-ideal solution with zero volume change on mixing.
The graph is a curve indicating an ideal solution with negative volume change on mixing.
Correct Answer
Detailed Explanation
According to Raoult's Law, a plot of vapour pressure against the mole fraction for an ideal solution is linear, indicating zero enthalpy and volume change on mixing.
