12.9: Chain Reactions. A large number of reactions proceed through a series of steps that can collectively be classified as a chain reaction. The reactions contain steps that can be classified as. These types of reactions are very common when the intermediates involved are radicals. An example, is the reaction.
Steps of Chain Reaction. A chain reaction proceeds by a sequence of three steps. Initiation: Formation of active particles or chain carriers by light, heat, or catalyst. Propagation: Active particles react with the original reactants, thereby creating more active particles, which initiate the next reaction. The number of active particles created is equal to the number consumed.

27 de sept. de 2023 · The faster the chain reaction — that is, the larger the number of U235 atoms that disintegrate each second — the faster energy is released and the hotter the fuel rods become. The uranium in a nuclear reactor is thoroughly mixed with neutral material and formed into pellets about half inch wide and three-quarters of an inch long.
