Question
Question: Which of the following is incorrect....
Which of the following is incorrect.
A
Relative lowering of vapour pressure is independent
B
The vapour pressure is a colligative property
C
Vapour pressure of a solution is lower than the vapour
pressure of the solvent
D
The relative lowering of vapour pressure is directly
propertional to the original pressure
Answer
The relative lowering of vapour pressure is directly
propertional to the original pressure
Explanation
Solution
According to Raoult's law, the relative lowering in vapour pressure of a dilute solution is equal to mole fraction of the solute present in the solution.
