Question
Question: Vapour pressure of a solution is....
Vapour pressure of a solution is.
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
Answer
Directly proportional to the mole fraction of the solvent
Explanation
Solution
For solutions containing non-volatile solutes, the Raoult’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.
