NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
A diagram shows a plot of vapour pressure versus mole fraction for an ideal solution at constant temperature. The plot has three lines: two dashed lines labeled I and II, and a solid line labeled III. Which component's partial pressure is represented by line II?
A
Component 1, the less volatile component
B
Component 2, the more volatile component
C
The total vapour pressure of the solution
D
The equilibrium mole fraction of component 1
Correct Answer
Option B
Detailed Explanation
In the plot, line II represents the partial pressure of the more volatile component, which is component 2, as it is directly proportional to its mole fraction (x2).
