Question

An exampke of decomposition reaction which is exothermic 0

Answer 1

Example of exothermic decomposition reaction

So, for example, the decomposition of ozone (O3) to atomic oxygen (O) is endothermic (+754.81 kJ/mole). both of exothermic and endothermic are depending on the chemical energy of the substances as a reactants whether this reaction is decomposition or other types of reactions.
