In an exothermic reaction heat is what
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 … WebAn exothermic reaction is the release of thermal energy (-ΔH) as it flows out of the system. Thermal energy is negative because energy is being released and the initial potential energy of reactants is more than the energy released from products. Let’s explore the exothermic reactions occurring around us: 1. Cellular Respiration
