Raoult's law definition with example
Hello student,
Raoult's Law :
The Raoult's law states that a solvent's partial vapour pressure in a solution or mixture is equal to the vapour pressure of a pure solvent multiplied by its mole fraction in the solution.
Mathematically, the law equation can be written as :
P
solution
= Χ
solvent
P
0
solvent, where...
P
solution
= vapour pressure of the solution
Χ
solvent
= mole fraction of the solvent
P0
solvent
= vapour pressure of the pure solvent
Thank you and good luck!
Hello candidate,
Raoult's law state that the partial pressure of any individual component of a mixture is equal to the partial pressure of the pure solution multiplied with the mole fraction of that individual component.
For example- let the total pressure of the solution be (P), and the mole fraction of A equals to x, then the partial pressure of A= x*P.
Hope this information was helpful!!
