Which of the following is the expression of Raoult’s law? (`p^(o)` = vapour pressure of pure solvent, `p^(s)` = vapour pressure of the solution)

A

`(p^(o) - p^(s))/(p^(o)) = (n)/(n+N)`

B

`(p^(s) - p^(o))/(p^(o)) = (N)/(N+n)`

C

`(p^(o) - p^(s))/(p^(o)) = (N)/(N-n)`

D

`(p^(s) - p^(o))/(p^(s)) = (N-n)/(N)`

Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : if a liquid solute more volatile than the solvent is added to the solvent, the vapour pressure of the solution is greater than vapour pressure of pure solvent. STATEMENT - 2 : Vapour pressure of solution is eqeal to vapour pressure of sovent.
