For an ideal solution, the total vapor pressure varies _____________ with the composition (expressed as mole fraction)?
Correct answer: C. Linearly
- A. Inversely
- B. Exponentially
- C. Linearly
- D. Negligibly
Explanation
Raoult's law gives the total pressure as the sum of each component's partial pressure, with each partial pressure proportional to its mole fraction. Hence, total vapour pressure varies linearly with composition.
