Respuesta :
Endothermic and exothermic reactions are based on energy absorption and energy release when the product formation occurs in a chemical reaction.
Highly endothermic reactions will need a lot of energy.
What are the endo and exothermic reactions?
The reaction in which the reactants absorbs the heat and energy from the system it is present to for the products is called the endothermic reaction.
The chemical reaction in which the heat is produced when the products are created is called the exothermic reaction.
Therefore, option A is correct.
