Answer 2

Answer:

Endothermic reaction : A chemical reaction which is accompanied by the absorption of energy is called an endothermic reaction.

Example: C (s) + 2S (s) + Heat → CS2(l)

Exothermic reaction : A chemical reaction which is accompanied by the release of energy is called exothermic reaction.

Example: CaO(s) + H2O(l) → Ca(Oh)2 (aq) + Heat energy
