The adsorption can be described by the Langmuir adsorption isotherm if lateral interactions are neglected.
2.
Surface phase dissociation constant KDsurf ( 3.84?.68 ) is obtained by fitting Langmuir adsorption isotherm on equilibrium signals.
3.
Assuming the Langmuir Adsorption isotherm still applied to the adsorbed layer, K _ { eq } ^ A is expected to vary with coverage, as follows:
4.
Hence, adsorption of gas molecules to the surface is more likely to occur around gas molecules that are already present on the solid surface, rendering the Langmuir adsorption isotherm ineffective for the purposes of modelling.
