Abstract
1. The adsorption energies of isolated molecules of different structure have been calculated, i.e., molecules of CO2, SO2, (CH3)2CO, and (C2H52O, on the surface of the basal face of graphite. The two terms in the potential of the electro-kinetic (dispersion) forces, the potential of the electro-static induction forces and the potential of the repulsive forces were calculated and were found to be close to the values of the differential heats of adsorption on graphitized carbon blacks, measured at small coverages of the surface. 2. The calculated mutual interaction energies of adsyrbate molecules for molecules of CO2, SO2, (CH32CO and (C2H52O in a dense monolayer for different packings with consideration of the energy of electro-kinetic, electrostatic-dipolar, electrostatic quadrupolar and repulsive interaction forces, are found to be in agreement with the experimental values of the rise in the heat of adsorption with coverage of the monolayer.
