Which is defined as an endothermic reaction

The heat that a chemical reaction gives off can quickly heat the surrounding area or rest of the chemicals in the container to very high temperature. As temperature increases, the rate of chemical reactions generally increase as well. Thus, once an exothermic reaction begins, it can quickly "run away" -- accelerating its rate because of the heat produced.

This can be especially dangerous if the material reaches its flash point or autoignition temperature , at which point a fire or explosion could occur. Therefore, it is very important to know when a chemical reaction can generate excess heat and to take appropriate measures to deal with this.

Examples include slow mixing, using a cooling bath, or avoiding that reaction. Most mixtures of incompatible chemicals involve violently rapid exothermic reactions. See also : autoignition temperature , flash point , oxidation.

The definition of endothermic is a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. Designating, of, or produced by a chemical change in which there is an absorption of heat.

From the Cambridge English Corpus. Factors such as torquing, gross mechanical plastic deformation, fracture and related structural phase changes and diffusion, spalling, endothermic reactions, melting, ablation, and vaporization reduce the effective momentum coupling.

Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Since the entropy increases with temperature, many endothermic reactions preferably take place at high temperatures.

In contrast, in endothermic reactions, heat is consumed from the environment. See all examples of endothermic reaction. These examples are from corpora and from sources on the web.
