Question

Why is decomposition of vegetable matter into compost considered an exothermic reaction?

Answer 1

Exothermic reaction:

• Exothermic reactions are those chemical reactions in which the exchange of heat takes place from the system to surroundings or heat is evolved during the reaction.
• Examples: Burning of a Candle, Rusting of Iron, and Burning of Sugar.

Decomposition of vegetable matter

• Decomposition of vegetable matter includes the breakdown of vegetable materials into compost.
• The decomposition process, carried out by bacteria, necessitates using energy to break down the chemical bonds and the overall reaction involves the evolution of heat.

Hence, the decomposition of vegetable matter into compost is considered an exothermic reaction.
