Difference between exothermic and endothermic reaction. Give an example for each.


i. The chemical reactions that absorb heat are called as endothermic reactions.
Example:
Photosynthesis is an endothermic reaction as plants absorb sun light energy to prepare their food.


ii. The chemical reactions that release heat are called as exothermic reactions.


Example:
Combustion is an exothermic reaction as lot of heat energy is released.
