Question

Which of the following is incorrect? (A) Relative lowering of vapour pressure is independent of the nature of the solute and the solvent (B) The ralative lowering of vapour pressure its 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 proportional to the original pressure

Tardigrade Admin · Accepted Answer

According to Raoult's law, the relative lowering of vapour pressure of a dilute solution is equal to the mole fraction of the solute present in the solution, i.e, (p-ps/p)=(n/n+N)

Q. Which of the following is incorrect?

Relative lowering of vapour pressure is independent of the nature of the solute and the solvent

The ralative lowering of vapour pressure its a colligative property

Vapour pressure of a solution is lower than the vapour pressure of the solvent

The relative lowering of vapour pressure is directly proportional to the original pressure

According to Raoult's law, the relative lowering of vapour pressure of a dilute solution is equal to the mole fraction of the solute present in the solution, $i . e,$
$\frac{p - p s}{p} = \frac{n}{n + N}$
