Which of these statements is true about endothermic reactions, but not about exothermic reactions?

a.) the reactants and products are different substances.
b.) the reactants have less energy than the products.
c.) the temperature of the container increases.
d.) no change in energy occurs.

B.) The reactants have less energy than the products.

Explanation: An endothermic reaction is a type of of chemical reaction in which energy is absorbed from the surrounding. The temperature of the surrounding decreases.

An Exothermic reaction is a type of of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.

In an endothermic reaction as the energy is absorbed by the reactants, thus the energy of the products is higher. The difference in the energies of the reactants and products is the energy which was being absorbed.

i'm just gonna leave this comment here, so i can get a challange done-
