The reaction in which a substance gains oxygen or loses hydrogen is called an oxidation reaction. For example, when copper (Cu) is heated in the presence of air, it gets oxidised to form copper oxide (CuO). The chemical equation involved in this reaction can be represented as Since heat energy is absorbed in this process, this reaction is endothermic nature.

Oxidation reaction may be endothermic or exothermic depend upon the nature of reactant Those oxidation reaction in which reactant are highly reactive give exothermic reaction. Exothermic: combustion of hydrocarbons, thermite rxn, burning a reactive metal for example sodium in air. Endothermic: burning a nitrogen in air. nitrogen is very less reactive so its oxidation become endothermic.
