Exothermic acid
WebFeb 20, 2024 · Exothermic reactions are chemical reactions that generate heat. The term exothermic is derived from the Greek words Exo, which means outside, and thermic, which means heat. As a result, exothermic heat is heat that moves outside. Exothermic reactions are significant in forensic science, notably in the examination of fires and explosions. WebApr 23, 2024 · I would thus guess that formation of most carboxylic esters from carboxylic acids and alcohols would be slightly exothermic or slightly endothermic depending on structure. The reasons esterifications are often heated are 1) to increase the rate of reaction and 2) to distill off water as it forms.
