Does a exothermic reaction release energy

WebAug 8, 2024 · Endothermic and Exothermic Reactions. 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 … WebThe temperature of the immediate surroundings rises as an exothermic process releases heat. An endothermic process absorbs heat from the environment and cools it. Endothermic reactions absorb energy in the form of heat from their surroundings. An exothermic reaction, on the other hand, discharges energy into the system's surroundings.
