Question

I'm 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

Answer 1

The answer would have to be D.

Answer 2

Answer: Option (B) is the correct answer.

Explanation:

A chemical reaction in which there is release of energy into the atmosphere is known as an exothermic reaction.

Also, energy of products is less than the energy of reactants for an exothermic reaction.

For example, A + B $\rightarrow$ C + D + Heat

Whereas a chemical reaction in which heat is absorbed by the reactant molecules is known as an endothermic reaction.

Also, energy of products is more than the energy of reactants in an endothermic reaction.

For example, A + B + Heat $\rightarrow$ C + D

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