Q. Which of the following is incorrect?
A) Relative lowering of vapour pressure is independent
B) Vapour pressure of a solution is lower than the vapour pressure of the solvent
C) The vapour pressure is a colligative property
D) The relative lowering of vapour pressure is directly proportional to the mole fraction solute
Explanation
(d)
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
