In a given chemical reaction, the energy of the products is less than the energy of the reactants. which statement is true for this chemical reaction?

a. energy is absorbed in the reaction.
b. energy is released in the reaction.
c. there is no transfer of energy in the reaction.
d. energy is lost in the reaction.

Option (B) is the correct answer.

Explanation:

A reaction in which heat energy is liberated by reactant molecules is known as an exothermic reaction.

For example,

In an exothermic reaction energy of reactant molecules is more than the energy of product molecules.

On the other hand, a reaction in which heat energy is absorbed by reactant molecules is known as an endothermic reaction.

For example,

In endothermic reaction energy of reactant molecules is less than the energy of product molecules.

Therefore, we can conclude that the statement energy is released in the reaction, is true for this chemical reaction.
