Popis: The correlation equations are discussed between entropy and enthalpy factors during complex heterogeneous catalytic reactions based on the dependence of the Gibbs energy on the surface coverage. The existence of the entropy heterogeneity in the adsorption layer leads to the correlations between ΔSθ and ΔHθ. In the cases where the increase of ΔHθ is accompanied by an increase of ΔSθ, i. e. when the entropy factors lead to a decrease of the interval of heterogeneity, the known thermodynamic compensation effect is observed.
