1. Any action in resisting other action or force; counter
tendency; movement in a contrary direction; reverse
action.
[1913 Webster]
2. (Chem.) The mutual or reciprocal action of chemical 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
manifestation of distinctive characters. See {Blowpipe
reaction}, Flame reaction, under Blowpipe, and
Flame.
[1913 Webster]
3. (Med.) An action induced by vital resistance to some other
action; depression or exhaustion of vital force consequent
on overexertion or overstimulation; heightened activity
and overaction succeeding depression or shock.
[1913 Webster]
4. (Mech.) The force which a body subjected to the action of
a force from another body exerts upon the latter body in
the opposite direction.
[1913 Webster]
Reaction is always equal and opposite to action,
that is to say, the actions of two bodies upon each
other are always equal and in opposite directions.
--Sir I.
Newton (3d Law
of Motion).
[1913 Webster]
5. (Politics) Backward tendency or movement after revolution,

The reaction may be primarily mental (" a reaction of
surprise") but is usually manifested by some activity.
[PJC]
Reaction time (Physiol.), in nerve physiology, the interval
between the application of a stimulus to an end organ of
sense and the reaction or resulting movement; -- called
also physiological time.
Reaction wheel (Mech.), a water wheel driven by the
reaction of water, usually one in which the water,
entering it centrally, escapes at its periphery in a
direction opposed to that of its motion by orifices at
right angles, or inclined, to its radii.
