TL;DR: In this paper, the partial oxidation of CH 4 over Rh/Al 2 O 3 was studied by means of temporal analysis of products (TAP), where CH 4 adsorb dissociatively on reduced metal sites and water adsorbed on the support acts as an oxygen source through the inverse spillover of water or hydroxyl onto the Rh particles.

TL;DR: In this paper, the authors use density functional theory with an explicit solvent model of the electrochemical interface to calculate activation energy barriers for various proton-electron transfer elementary reactions steps for CO2 reduction on Au, Cu, and Pt surfaces.

TL;DR: In this article, the process of bimolecular reaction between A and B is given by Eq. (1), taking into account the diffusion step bringing the two reactions in proximity.
Abstract: Chemical reactions require that at least two molecules or reacting groups come into close proximity so that energy, electrical charge, or chemical groups may be exchanged between them. The process of bimolecular reaction between A and B is given by Eq. (1), taking into account the diffusion step bringing the two reactions in proximity, (AB)

TL;DR: In this paper, the thermodynamic activity of an atomic species on the surface of a catalyst and its determination under steady-state conditions of a catalytic reaction is discussed, and a rational rate law is proposed to represent the empirical rate data in a more logical form than an empirical rate law.
Abstract: Publisher Summary This chapter discusses the thermodynamic activity of an atomic species on the surface of a catalyst and its determination under steady-state conditions of a catalytic reaction. If the rate of an individual step of a catalytic reaction depends on the concentration of adsorbed atoms occurring as intermediates, it is imperative to determine this dependence. The determination of the surface concentration of molecules adsorbed on a catalyst is feasible under favorable conditions. In the case of atomic species, it has been found to be convenient to use the thermodynamic activity rather than the surface concentration as the relevant variable. The primary problem of chemical kinetics is the formulation of an empirical rate law that represents the rate of a reaction as a function of the concentrations or partial pressures of reactants, products, and catalysts present in a gaseous or liquid phase. The knowledge of the mechanism of a reaction may be used to formulate a rational rate law that may represent the empirical rate data in a more logical form than an empirical rate law.
