it is not necessary that all combination reactions will be exothermic. Whether a reaction is exothermic or endothermic depends upon the nature of the reactants and the energy released in bond breaking and bond formation. This determines the overall enthalpy of the reaction. We can say that most of the combination reactions are exothermic, but each and every combination reaction will not be exothermic. For example, the uncatalysed synthesis of NO from N2 and O2 is endothermic.
N2 + O2 → 2 NO
Similarly, most of the decomposition reactions are endothermic. However, it is not necessary that all decomposition reactions will be endothermic.
N2 + O2 → 2 NO
Similarly, most of the decomposition reactions are endothermic. However, it is not necessary that all decomposition reactions will be endothermic.
