WebThe Henry’s law constant H is a proportionality coefficient describing the distribution between these phases. It can be defined either as the ratio Q l / Q g (related to solubility) or its inverse Q g / Q l (related to volatility). Both choices are in common use, and the resulting Henry’s law constants are reciprocals of each other.
