✦ Synopsis

Equilibrium adsorption and the flux of adsorbable gases through porous media with homogeneous surfaces have been of experimental interest for many years. A number of theoretical models have addressed this system as the initial case for more complex situations. However, most of these thmries do not attempt to represent all possible cases with a single model based on statistical mechanics and utilizing intermolecular potential parameters. Instead, only one property or type of system is considered.

Part I (Lee and OConnell, 1985) has developed a fully generalized theory that includes the essential molecular phenomena and formulates expressions for all the measurable properties of pure and mixed systems at submonolayer coverages. The present paper describes application of the model to gases physically adsorbed on graphitized carbon blacks with surfaces that are essentially homogeneous. Difficulties and inconsistencies of data analysis are discussed and a strategy for fitting the several molecular parameters to the data is indicated.
