Is the breaking of bonds endo or exothermic
Did you know?
WitrynaEnergy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process. Whether … WitrynaExo - means “out” and endo - means “in.” Based on the words, it would make perfect sense if exothermic meant “thermal energy out” and endothermic meant “thermal energy in.”. However, there are many categories of energy, like light and sound, that can be involved in reactions. So, exothermic means “energy of any kind out” and ...
