WebExothermic is energy that is released when any chemical bond is formed and Endothermic is energy which must be added when a chemical bond is broken. It is recognized that with exothermic reactions, the products will contain a lower energy with the reactants. WebMost standard enthalpy of formation values are negative, indicating that the formation of most compounds from their elements is an exothermic process. Those compounds that have positive values are most likely unstable You can use this data to help you figure out the relative stabilities of compounds.
