How to Calculate Endothermic and Exothermic Reactions

WebChemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or … WebDistinguish between endothermic and exothermic reactions Key Points All chemical reactions involve the transfer of energy. Endothermic processes require an input of energy to proceed and are signified by a positive change in enthalpy. Exothermic processes release energy upon completion, and are signified by a negative change in enthalpy.
