WebPart 3: Most reactions are accompanied by some energy changes. Frequently, the energy is in the form of heat. If heat is absorbed during the reaction it is referred to as endothermic and if heat is released, it is exothermic. In an endothermic reaction, heat can be considered a reactant and in an exothermic reaction heat is considered a product.

WebAug 8, 2024 · Endothermic and exothermic reactions can be thought of as having energy as either a reactant of the reaction or a product. Endothermic reactions require energy, so energy is a reactant. Heat flows from the surroundings to the system (reaction mixture) and the enthalpy of the system increases ( ΔH is positive). WebIn an endothermic reaction, energy can be considered as a reactant of the reaction. In an exothermic reaction, energy can be considered as a product of the reaction.
