Which of these describes an exothermic reaction?
a. energy is transferred by the reaction
b. no energy is absorbed by the reaction
c. energy is released by the reaction
d. energy is created by the reaction

A nswer: -

C. Energy is released by the reaction

Explanation:-

An exothermic reaction is one in which during the progress of the reaction heat is evolved.

So energy is released by the reaction.

It cannot be created as energy is neither created nor destroyed as per the Law of conservation of energy. Energy is not transferred either.

The energy released during the progress of the reaction originates from the chemical bonds of the reactants as they break during their conversion into products.
