Question

State the following:
(i) Raoult’s law in its general form in reference to solutions.
(ii) Henry’s law about partial pressure of a gas in a mixture.

Answer 1

(i) Raoult’s law: It states that for any solution, the partial pressure of each volatile component in the solution is directly proportional to its mole fraction.
(ii) Henry’s law: It states that the partial pressure of a gas in vapour phase (P) is proportional to its mole fraction (x) in the solution.
