Answer: The given reaction is a type of endothermic reaction.
Explanation:
There are 2 types of reaction classified on the basis of heat released or absorbed:
1. Exothermic reactions: In these reactions, the heat is released because the energy of products is less than the energy of the reactants. for these reactions is negative.
2. Endothermic reactions: In these reactions, heat is absorbed by the reactants because the energy of the products is more than the energy of the reactants. for these reactions if positive.
In the given question, the energy of the products is greater than the energy of the reactants. Hence, this is considered as a type of endothermic reaction.
