Abstract
Thermodynamic principles for the calculation of differential heats of excess and absolute adsorption were considered. A set of isosteres of excess adsorption of krypton on zeolite NaA are presented, from which the coverage and temperature dependences of the heats of excess adsorp tion are calculated and analyzed. The reasons for infinitely high valu es of the excess heats at finite values of adsorption are discussed. T he problems of recalculation of the excess adsorption to absolute adso rption are considered.
