Question

1. Define Raoult's law? Expression in liq & vapour state
​

Answer 1

Answer:

Raoult's law states that a solvent's partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution. Mathematically, Raoult's law equation is written as; Psolution =

Answer 2

Answer:

Raoult's law states that vapour pressure of the solvent in a solution is the product of mole fraction of solvent and vapour pressure of the pure solvent. The mathematical expression of Raoult's law is as follows: Psolution=Xsolvent×P∘solvent. Here, Psolution= vapour pressure of the solution.
