TL;DR: In this article, the transient kinetics of the various elementary reactions that may limit the steady state rate of the CO and O2 to form CO2 over Ir(110) have been studied through measurements of the transient kinetic kinetics, including desorption, oxidation, and adsorption of CO and oxygen.

TL;DR: In this paper, the authors derived equations for the rates of unimolecular and bimolecular heterogeneous gas reactions under various conditions of surface coverage by either reactants or poisons.
Abstract: The method developed in the preceding paper is used to derive equations for the rates of unimolecular and bimolecular heterogeneous gas reactions under various conditions of surface coverage by either reactants or poisons. The resulting equations are of the same form as those previously deduced by Langmuir and others, but they are more explicit; provided the activation energy is known they can be utilized to calculate rates of surface reactions which are in good agreement with the observed values. In the case of the dissociation of hydrogen on a tungsten surface, the simple assumption that the activated state consists of hydrogen atoms permits the absolute rate of the reaction to be calculated with an accuracy which is at least as good as that attained by direct experimental measurement. The factors responsible for the difference in rates of the same reaction taking place homogeneously or heterogeneously are considered; it is shown that adsorption of the activated complex lowers the over‐all activation energy, and this has the most important influence in favoring the surface reaction. If one of the products, or any other substance acting as a poison, is strongly adsorbed, the effective activation energy is increased, but there is some compensation resulting from the increase of entropy accompanying the desorption of the poison.

TL;DR: In this article, a linear concentration gradient method was applied to find and measure the region of oscillations in the parametric plane of the inflow concentrations of bromate and bromide.
Abstract: In the present paper we report on the discovery and some initial investigations of sustained limit cycle oscillations in the stirred flow oxidation of cerous ions by acidic bromate. In order to find and measure the region of oscillations in the parametric plane of the inflow concentrations of bromate and bromide, a linear concentration gradient method was applied. At present the described flow oxidation is the simplest chemical oscillator fully understood in terms of elementary reaction steps.

TL;DR: In this paper, a C++ program was developed to assess ReaxFF trajectories and to analyze elementary reactions involved in the CO 2 gasification process of lignite, and the calculated overall enthalpy and entropy changes could clearly explain the experimental data.

TL;DR: In this article, the effect of the compositions of flue gas on Hg0 oxidation was investigated and the reaction orders of Hg 0 oxidation over V2O5-WO3/TiO2 in regard to both the concentrations of hg 0 and HCl in gas phase were approximately 0.
