Write similarity between Raoult's law and Henry's law

Explanation

According to Raoult.s law , the vapour pressure of a volatile component in a given solution is given by
`p_(1) = x_(1) p_(1)^(o+)`
In the solution of a gas in a liquid, one of the components is so volatile that it exists as a gas then its solubility is given by Henry.s law which states that
`p= K_(H) x`
If we compare the equations for Raoult.s law and Henry.s law , it can be seen that the partial pressure of the volatile component or gas is directly proportional to its mole fraction in solution . Only the proportionality constant `K_(H)` differs from `p_(1)` . Thus, Raoult.s law becomes a special case of Henry.s law in which `K_(H)` becomes equal to `p_(1)^(o+)`
