2. (Chem.)
(a) A process by which a chemical reaction is accelerated
in the presence of certain agents which were formerly

formation of an intermediate compound or compounds, so
that by alternate composition and decomposition the
agent is apparenty left unchanged; as, the catalysis
of making ether from alcohol by means of sulphuric
acid; or catalysis in the action of enzymes (as
diastase, or ptyalin) on starch.
(b) The catalytic force.
