During a chemical reaction:
Bonds in the reactants are broken. New bonds are made in the products.
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.
If more heat energy is released when making the bonds than was taken in, the reaction is exotheric. If more heat energy was taken in when making the bonds than was released,…
