Question

is oxidation an endothermic or an exothermic reaction​

Answer 1

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. nitrogen is very less reactive so its oxidation become endothermic.

Answer 2

Answer:

Explanation:

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 nitrogen in air.

nitrogen is very less reactive so its oxidation become endothermic.
