Abstract
Dependences of the Helmholtz energy, entropy, and internal energy in single micropores on the total number of guest molecules and the oxygen to nitrog en ratio were found by analysis of experimental data on adsorption of the b inary oxygen-nitrogen mixture on zeolite NaX using the statistical model. A substantially non-ideal character of the adsorption phase, which exhibits negative deviations from Raoult's law, can result from heterogeneity of the adsorption field inside single cavities.
