During chemical reactions, atoms and molecules regroup and form new constellations. When molecules formed during a reaction readily react with molecules present from the beginning, a chain reaction can occur. Explosions and fire are examples of chain reactions. During the 1930s Cyril Hinshelwood analyzed conditions and sequences of events involved in chain reactions from a theoretical standpoint. Among other things, he found that the theoretical results corresponded with observations of the reaction between hydrogen and oxygen.
