Preferred Label : molecularity;
IUPAC definition : The number of reactant molecular entities that are involved in the 'microscopic chemical
event' constituting an elementary reaction. (For reactions in solution this number
is always taken to exclude molecular entities that form part of the medium and which
are involved solely by virtue of their solvation of solutes.) A reaction with a molecularity
of one is called 'unimolecular', one with a molecularity of two 'bimolecular' and
of three 'termolecular'.;
