Chemically Termolecular Reaction (IMAGE)
Caption
A chemical reaction where three different molecules (e.g. H, O2, H) each participate in the breaking and forming of chemical bonds. The reaction is mediated by an ephemeral collision complex (HO2**) formed from the collision of two molecules (H, O2) which then reacts upon colliding with a third molecule (H). Data from advanced computations reveal that reactions of this class, hypothesized nearly a century ago and then later assumed to be unimportant, are major chemical pathways.
