Giselle Rodriguez · Answer 1

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.
