If energy is absorbed because of a chemical reaction the reaction is a product, exothermic, limiting, endothermic.

If energy is absorbed because of a chemical reaction the reaction is Endothermic.

Option D

Explanation:

There are two types of chemical reaction depending upon whether the energy is absorbed or released to the surroundings. When the energy is absorbed in a reaction from the surroundings it is called as an endothermic reaction and the temperature of the surroundings gets affected.

When the opposite reaction occurs in the surroundings, it is called as an exothermic reaction. Option A and B are irrelevant to the situation here. So if the energy is absorbed because of a chemical reaction then the reaction is said to be endothermic.
