Question

decomposition of organic matter is it endothermic or exothermic​

Answer 1

Organic compounds decompose in air (oxygen) to give mostly carbon dioxide and water, both and particularly the latter being highly exothermic. ... There is one kind of decomposition reaction which is always endothermic; the decomposition of gaseous diatomic or polyatomic molecules into gaseous atoms.

Answer 2

Answer:

exothermic

Explanation:

the decomposition of vegetable matter or organic matter is an example of exothermic reaction. Like every exothermic reaction heat is evolved when the matter is decomposed. It remains unnoticiable because the reaction that takes place is a slow reaction.
