Question

• Define Exothermic Reaction?​

Answer 1

Explanation:

An exothermic reaction is a chemical reaction where the substances reacting release energy as heat. An example of this is combustion. Exothermic reactions transfer energy to the surroundings. The reaction that does the complete opposite (it absorbs heat) is an endothermic reaction.

Answer 2

$answer \: -$

An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones. ... Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic.
