Answer:
The reaction is exothermic.
Explanation:
Enthalpy of Formation (ΔHrxn):
It is regarded as the variation in enthalpy when a mole of substance is produced at standard temperature and pressure through its pure elements under same conditions.
1) ΔHrxn = negative
When the energy is produced in the course of production of compound in a chemical reaction. It is known as Exothermic reaction.
2) ΔHrxn = posituve
When the energy taken in in the course of the production of compound in a chemical reaction. It is known as Endothermic reaction
The of production of carbon dioxide is negative. It implies that the ΔHrxn is an exothermic reaction.
