Question
State the formula relating pressure of a gas with its mole fraction in a liquid solution in contact with it.
Solution
solution:
Pgas = Mole fraction gas of gas x KH, where KH is Henry law constant
⇒ p = KH.x where ‘x’ is mole fraction.
The most commonly used form of Henry’s law states that “the partial pressure of the gas
in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution”
Pgas = Mole fraction gas of gas x KH, where KH is Henry law constant
⇒ p = KH.x where ‘x’ is mole fraction.
