How do chemists determine reaction mechanisms
WebOnce a sane/reasonable reaction mechanism or two has been determined in this way (and an appropriate solvent or reaction environment), chemists are trained to be able to draw conclusions about how to the kinetics and thermodynamics of the reaction should play out based on the energetics of reactants, products and key intermediates. WebJan 5, 2024 · Updated on January 05, 2024. A reaction or chemical reaction is a chemical change which forms new substances. In other words, reactants react to form products that have a different chemical formula. …
