If we read the reaction as X + Y → Z + Q it is
A. endothermic
B. exothermic

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. [tex]\Delta H[/tex] 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. [tex]\Delta H[/tex] 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.
