composite reaction
A
chemical reaction
for which the expression for the
rate of disappearance
of a reactant (or
rate of appearance
of a product) involves rate constants of more than a single
elementary reaction
. Examples are '
opposing reactions
' (where rate constants of two opposed chemical reactions are involved), '
parallel reactions
' (for which the
rate of disappearance
of any reactant is governed by the rate constants relating to several
simultaneous reactions
to form different respective products from a single set of reactants), and
stepwise reactions
.
