Type: MCQ-conceptual-Easy-Class 12
Which of the following statements about the vapor pressure and composition of an ideal solution is correct?
A
The total vapor pressure increases with increasing mole fraction of the more volatile component.
B
The vapor pressure of a component is independent of its mole fraction in the solution.
C
The vapor phase composition is solely determined by the total vapor pressure.
D
The partial pressure of a component is inversely proportional to its mole fraction in the solution.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the total vapor pressure of an ideal solution is directly proportional to the mole fraction of the more volatile component, illustrating the relationship between vapor pressure and composition.
