Chemistry-Raoult's Law
NEET Chemistry Raoult's Law MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a plot where the x-axis represents the mole fraction of the solvent and the y-axis represents the vapor pressure of the solution. Which label correctly identifies the point where the vapor pressure equals the vapor pressure of the pure solvent?
A
Point where the mole fraction of the solvent is 1
B
Point where the mole fraction of the solvent is 0
C
Point where the vapor pressure is half of the vapor pressure of the pure solvent
D
Point where the vapor pressure exceeds the vapor pressure of the pure solvent
Correct Answer
Option A
Detailed Explanation
According to Raoult's law, the vapor pressure of the solution equals the vapor pressure of the pure solvent when the mole fraction of the solvent is 1.
