The proportionality constants between the gas pressure and occupancy of the idealized talc surface were computed for noble gases Helium, Neon, Argon, Krypton and Xenon covering the temperature range 100 K - 450 K. Interaction potencial noble gas atom - solid phase was calculated using summation of interaction potencials of Lennard-Jones type. The values of Henry´s constants of adsorption were calculated using known formula based on computation of configuration integral. The one-particle configuration integral was calculated using the classical mechanics limit. The assumption of ideality of both, free gas and adsorbed phase, was used. The obtained values of Henry´s constant are in quantitative agreement with the values estimated from experimental absorption isotherms for analogical systems.
