Which of the following is the expression of Raoult’s law?
(

{p = }

vapour pressure of pure solvent,

{{p_s}}

=vapour pressure of the solution)

View answer and explanation

Correct option: A

\frac{{p - {p_s}}}{p} = \frac{n}{{n + N}}

Option A is the correct expression of Raoult's law, relating the relative lowering of vapor pressure to the mole fraction of the solute.
