The Stress Dependence of Adsorption
Abstract
Considering a gas-solid adsorption system, we present a simple analysis of the changes in the chemical potential of the adsorbed gas as the substrate solid is subjected to external forces. Using the canonical partition function, we show that the chemical potential varies with applied stress which variation we call the chemostress coefficient. Numerical values obtained for these coefficients indicate that the magnitude of the effect depends sensitively on the solid-gas interaction potential which in turn depends on the changes of the polarizabilities and of excitation energies of the solid.
