The given chemical reactions should be identified as exothermic and endothermic. Concept Introduction : An exothermic reaction can be defined as the chemical reaction which releases energy during the formation of product therefore the energy value must be written with product molecules in the balance chemical reaction. An endothermic reaction can be defined as the chemical reaction which absorbs energy during the formation of product therefore the energy value must be written with reactant molecules in the balance chemical reaction.
