Answer:
Answer to the question:
Step-by-step explanation:
Exothermic Reaction
It is called an exothermic reaction to any chemical reaction that releases energy, either as light or heat, or what is the same: with a negative variation of enthalpy; that is to say: ΔH < 0. Therefore it is understood that exothermic reactions release energy.
Endothermic Reaction
It is called an endothermic reaction to any chemical reaction that absorbs energy, usually in the form of heat.
If we talk about enthalpy (H), an endothermic reaction is one that has a variation of enthalpy ΔH> 0. That is, the energy possessed by the products is greater than that of the reagents.
