agents
upon each
other,
or the
action
upon such
chemical
agents
of some form of
energy,
as heat,
light,
or
electricity,
resulting
in a
chemical
change
in one or more of these
agents,
with the
production
of new
compounds
or the

Catalysis
::
Catalysis
(n.) A
process
by which
reaction
occurs
in the
presence
of
certain
agents
which were
formerly
believed
to exert an
influence
by mere
contact.
It is now
believed
that such
reactions
are
attended
with the
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
soluble
ferments
(as
diastase,
or
ptyali
Passive

Designating
certain
morbid
conditions,
as
hemorrhage

and
tissues,
with

vitality
and lack of
reaction
in the
affected
tissues..
