"The equilibrium value of the mole fraction of the gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid surface". This statement pertaining to the solubility of gases in liquid is the ______________ law?
Correct answer: B. Henry's
- A. Raoult's
- B. Henry's
- C. Amagat's
- D. None of these
Explanation
Henry’s law states that, at dilute concentrations, the equilibrium dissolved concentration or mole fraction of a gas is proportional to its partial pressure above the liquid. Raoult’s law instead relates a liquid component’s vapour pressure to its liquid-phase mole fraction.
