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
Correct Answer: D
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.
