Experimental data on (E)-2,3-diphenylpropenoic acid hydrogenation over Pd were used to illustrate the applicability of the advanced model. The key features for a system to display such unusual behavior are associated with rate constants for steps involving one modifier being dependant on the concentration of the other one.
