Question

Which statement is true?


In an endothermic reaction, the energy of the products is the same as the energy of the reactants.


In an endothermic reaction, the energy of the products is less than the energy of the reactants.


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


In an exothermic reaction, the energy of the products is the same as the energy of the reactants.

Answer 1

Answer:

The correct answer is in an exothermic reaction the energy of the product is less than the energy of the reactants.

Explanation:

Exothermic reaction is a type of reaction that generates heat.As a result in case of an exothermic reaction the energy of the reactant is more than the energy of the product.

       That"s why the enthalpy change in an exothermic reaction is always positive .

Answer 2

The correct answer is C. In an exothermic reaction, the energy of the products is less than the energy of the reactants.

Explanation:

A chemical reaction is a process during which two or more substances interact and form new products. In these, the first substances are known as the reactants while the substances at the end of the reaction are the products. Moreover, reactions often involve a change in the energy of substances this known as enthalpy.

In the case of exothermic reactions in which energy or heat is released, the enthalpy is negative, this means, the energy in the products is less than in the reactants because during the chemical reaction substances release energy. This makes option C correct. On the other hand, in endothermic reactions, energy is absorbed, and therefore it is expected energy in the products is more than the one in the reactants.
