Question

An exothermic reaction _____.

A.takes more time than an endothermic reaction.
B.releases more energy than it uses.
C. releases less energy than it uses.
D. does not require activation energy.

Answer 1

c. releases less energy than it uses

Answer 2

Answer : The correct option is, (B) releases more energy than it uses.

Explanation :

Endothermic reaction : It is defined as the chemical reaction in which the energy is absorbed from the surrounding.

In the endothermic reaction, the energy of reactant are less than the energy of product.

Exothermic reaction : It is defined as the chemical reaction in which the energy is released into the surrounding.

In the exothermic reaction, the energy of reactant are more than the energy of product.

Hence, the correct option is, (B) releases more energy than it uses.
