How would you campare Raoult's law and Henry's law.

Explanation

(i) According to Raoult.s law, for a solution containing a non volatile solute,
`P _("solute")=P _("solute"^(0) x _("solute")`
(ii) According to Henry.s law, `P_("solute")=K_(H),x_("solute")` in solution
(iii) The difference betwwn the abouve two laws is the proportionality constant `P^(@)` (Raoult.s law) and `K_(H)` (Henry.s law).
(iv) Henry.s law is applicable to solution containing gaseous solute in liquid solvent, while Raoult.s law is applicable to non volatile solid solute in the liquid solvent.
(v) If the solute is non volatilethen the Henry.s law constant will become equal to the vapour pressure of puire solvent `P^(@),` thus Raoult.s law becomes a special case of Henry.s law.
(v) For very dilute solutions, the solvent obeys Raoult.s law and the solute obeys Henry.s law.
