WebFlag. Peterson. 9 years ago. Thermodynamics, simply defined, is the branch of physics that deals with the conversion of different forms of energy, and the relations between heat … Thermodynamic reaction control or kinetic reaction control in a chemical reaction can decide the composition in a reaction product mixture when competing pathways lead to different products and the reaction conditions influence the selectivity or stereoselectivity. The distinction is relevant when product A forms faster than product B because the activation energy for product A is lower than …
WebThe kinetic and thermodynamic aspects of the surface phase structure evolution of an fcc MoC (001) surface under a H 2 O/H 2-rich atmosphere typically found during steam reforming processes were systematically studied via periodic density functional theory (DFT) and ab initio thermodynamic methods.
