In chemical reactions, energy must be supplied to break the bonds between atoms in the reactants.
When new bonds are formed between atoms in a chemical reaction, energy is released.
In an exothermic reaction, the energy released when new bonds are formed is less than the energy absorbed when bonds are broken.
In an endothermic reaction, the energy released when new bonds are formed is less than the energy absorbed when bonds are broken.
We can calculate the overall energy change in a chemical reaction using bond energies.
