Question

If the vapor pressure of component 1 is 30kPa and the henrys law constant of component 2 is 100 kPa, the mole fraction of component 2 in the gas phase does not exceed 20% when its mole fraction is 5% in the liquid phase. True or False?

Answer 1

Mole fraction of gas 2 in vapor phase is 14%.

So given statement is true that it will not exceed 20%.

Note : In case of multicomponent liquid gas equilibrium, partial pressure of any gas is equal to its vapor pressure.
