Chemical Chain - an overview ScienceDirect Topics

WebA branching chain is a type of chain that is used in the reaction mechanism when the reaction mechanism involves a unique sort of chain. According to scientific literature, the following reaction is known to occur in a hydrogen-oxygen explosion: H + O2 = HOH + O. In 1913, the German chemist Max Bodenstein first put forth the idea of chemical chain reactions. If two molecules react, not only molecules of the final reaction products are formed, but also some unstable molecules which can further react with the parent molecules with a far larger probability than the initial reactants. (In the new reaction, further unstable molecules are formed besides the stable products, and so on.) WebChain reactions have an initiation step where free radicals are produced, followed by chain propagation steps where the reaction of free radicals with closed shell species produces new radicals. Eventually the reactive species are removed from the reaction medium in termination steps. check balance on gift cards online outback

WebA possible nuclear fission chain reaction: 1) A uranium-235 atom absorbs a neutron, and fissions into two (fission fragments), releasing three new neutrons and a large amount of binding energy. 2) One of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction. WebIn chain reaction (2) Propagation, whereby the intermediate reacts with the original reactants, producing stable products and another intermediate, whether of the same or different kind; the new intermediate reacts as before, so a repetitive cycle begins.
