In an exothermic reaction heat is what
WebApr 23, 2024 · An exothermic reaction is one which results in heat or light being released by the system and absorbed into the surroundings, usually referred to as a change in enthalpy. Enthalpy H is the energy contained within the bonds of a molecule. This amount, the bond energy, is roughly the amount of enthalpy necessary to break the bond. Important Concept! WebAn exothermic reaction is a type of chemical reaction that releases heat to its surroundings, resulting in an increase in temperature of the surroundings. In an exothermic reaction, the energy released when new chemical bonds are formed in the products is greater than the energy required to break the chemical bonds in the reactants. As a result, the reaction …
