Raoult's law is a special case of Henry's law. Explain .

Text Solution

Verified by Experts

According to Raoult.s law, the vapour pressure of a volatile component is given as , `p = p^@ X`.
According to Henry.s law, the partial solubility of a component is given as, `p = K_H X`.
Comparing these equations, partial pressure is directly proportional to the mole fraction of component in solution. Only the proportionalty constants `p^@` and `K_H` differ.
When `K_H` becomes equal to `p^@`, Henry.s law becomes Raoult.s law.
