Question

Which of these describes an endothermic reaction?

Energy is released by the reaction.

Energy is absorbed by the reaction.

No energy is transferred by the reaction.

Energy is created in the reaction.

Answer 1

In Endothermic reactions, energy is absorbed. 

Answer 2

Answer: Energy is absorbed by the reaction.

Step-by-step explanation:

In endothermic reaction the energy is absorbed from the surroundings.

For example:

• Reaction occurring during the process photosynthesis is also an endothermic reaction in which glucose and oxygen are obtained as product from carbon dioxide and water by absorbing the energy from sunlight.

`6CO_2+6H_2O+\text{ sunlight}\rightarrow C_6H_(12)O_(6)+O_2`
