Raoult's law

Vedclass · Answer

(C) The given statement defines Raoult's law for solutions containing non-volatile solutes.According to Raoult's law,the relative lowering of vapour pressure is given by the expression: $\frac{P^0 - P}{P^0} = X_{solute}$Where:$P^0$ = Vapour pressure of pure solvent$P$ = Vapour pressure of the solution$X_{solute}$ = Mole fraction of the soluteThis shows that the relative lowering of vapour pressure is directly proportional to the mole fraction of the non-volatile solute.

"Relative lowering in vapour pressure of a solution containing a non-volatile solute is directly proportional to the mole fraction of the solute". The above statement is:
