The enthalpy change of the given reaction is negative, so the reaction is an exothermic reaction.

What is enthalpy change of a reaction?

Enthalpy change of a reaction is the energy changes that occur when reactant molecules form products.

Enthalpy is the heat content of a substance.

When enthalpy change is positive, the heat content of the product is greater than that of the reactant and the reaction is an endothermic reaction.

Whereas, when enthalpy change is negative, the heat content of the reactant is greater than that of the product and the reaction is an exothermic reaction.

Therefore, since the enthalpy change of the given reaction is negative, the reaction is an exothermic reaction.
