Chemical reaction - Wikipedia, the free encyclopedia (1242 words) |
 | A chemical reaction is a process involving one, two or more substances (called reactants), characterized by a chemical change and yielding one or more product(s) which are different from the reactants. |
| Classically, chemical reactions encompass changes that strictly involve the motion of electrons, although the general concept of a chemical reaction (in particular the notion of a chemical equation) is applicable to transformations of elementary particles, as well as nuclear reactions. |
| Reaction rates are related to the concentrations of substances involved in reactions, as quantified by the law of mass action. |
| Reaction - Wikipedia, the free encyclopedia (141 words) |
| In physics, a reaction is defined by Newton's third law: "For every action there is an equal and opposite reaction". |
| In politics, the reaction is the attitude of the reactionaries, or their political movement. |
| In risk management, the reaction is a response after the hazard. |
