Henrys law constant pce
WebIn a given solvent, the Henry’s constant for solute i, H i, is defined as an infinite-dilution limit: where f iand x iare the fugacity and the mole fraction of the solute, respectively. (Variables other than mole fraction are sometimes used to describe the amount of solute; this will be discussed later.)
