In both endothermic and exothermic reactions
WebAug 22, 2024 · A chemical reaction in which the heat is absorbed is called an endothermic reaction. This reaction causes a fall in temperature. Exothermic reactions cannot occur spontaneously. For this reaction to occur, external energy must be supplied. Examples of Endothermic Reactions Example 1: Photosynthesis WebJun 22, 2024 · Endothermic reactions absorb heat to bring on a chemical change. Photosynthesis, evaporation, sublimation, and melting ice are great examples. Exothermic reactions are chemical changes that release heat. Combustion and oxidation are the more common examples of this.
