Gas Temperature KH(K bar) He 293 144.97 N2 293 76.48 O2 293 34.86 The higher the value of Henry’s law constant, the lower is the solubility of the gas in the liquid

Q. Molar solubility of helium, nitrogen and oxygen are plotted against partial pressure o f the gas at constant temperature.
Henry’s law constant for these gases will lie in the following sequence?

$O_{2} > N_{2} > He$

$O_{2} < N_{2} < He$

$O_{2} = N_{2} = He$

$O_{2} > N_{2} < He$

Gas Temperature $K_{H}$ (K bar)

He 293 144.97

$N_{2}$ 293 76.48

$O_{2}$ 293 34.86

The higher the value of Henry’s law constant, the lower is the solubility of the gas in the liquid

Q. Molar solubility of helium, nitrogen and oxygen are plotted against partial pressure o f the gas at constant temperature. Henry’s law constant for these gases will lie in the following sequence?

O2​>N2​>He

O2​<N2​<He

O2​=N2​=He

O2​>N2​<He
