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.
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.

A chemical transformation or change brought about by the interaction of two substances.
Defined by a group of reactant molecules, a group of product molecules, and their respective stoichiometric coefficients. Often expressed in the form: aA + bB + ... - qQ + rR + ... The reaction is typically stoichiometrically balanced, but in special cases, unbalanced reactions will be allowed if the "balanced" stoichiometric flag is set to false (e.g., MW growth reactions where tracking hydrogen is not useful or desired).
In chemistry, any process in which the arrangement of atoms into molecules is changed.
in chemistry, a change or transformation in which a substance decomposes, combines with other substances, or interchanges constituents with other substances.
A regular or characteristic response to a stimulation of the nerves.
A counterforce imparted to a speaker enclosure in response to the air resistance to the motion of a moving diaphragm or cone. On a thick carpet, a reacting enclosure will rock slightly back and forth, impairing LF quality and overall detail. See "spike."
a response that reveals a person's feelings or attitude; "he was pleased by the audience's reaction to his performance"; "John feared his mother's reaction when she saw the broken lamp"
a bodily process occurring due to the effect of some foregoing stimulus or agent; "a bad reaction to the medicine"; "his responses have slowed with age"
an event that converts inputs to outputs in a single step
an incomplete, partial or frozen mind/body movement based on fear/guilt of a past-oriented event
Any general biochemical or molecular event.
