Solutions Question 110
Question: Vapour pressure of a solution is [EAMCET 1988; MP PET 1994]
Options:
A) Directly proportional to the mole fraction of the solvent
B) Inversely proportional to the mole fraction of the solute
C) Inversely proportional to the mole fraction of the solvent
D) Directly proportional to the mole fraction of the solute
Show Answer
Answer:
Correct Answer: A
Solution:
For solutions containing non-volatile solutes, the Raoul’s law may be stated as at a given temperature, the vapour pressure of a solution containing non-volatile solute is directly proportional to the mole fraction of the solvent.
