If energy is stored in chemical bonds, and bond formation is always an exothermic process, doesn't that imply that bond formation both stores and releases energy? How is this possible? I'm clearly not understanding some basic tenet of chemistry. For example, H+ and OH- neutralize to form H2O.
Most chemical reactions involve the breaking and formation of chemical bonds. It takes energy to break a chemical bond but energy is released when chemical bonds are formed. If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic. On the other hand if the reaction consumes more energy than it releases then the reaction absorbs heat and is said to be endothermic. Most reactions are exothermic. The amount of heat generated by a reaction can be quantified. The quantity that specifies the amount of heat is known as the enthalpy . If is positive then the reaction is endothermic and if it is negative the reaction is exothermic.
