Difference between Endothermic and Exothermic Reaction

Endothermic vs. Exothermic Reaction

What is difference between endothermic and exothermic reaction? When the molecules interact with each other several reactions take place. These reactions are divided into two groups according to their characteristics. They can be exothermic and endothermic reactions. Below this post is all about the difference between endothermic and exothermic reaction.

Difference between Endothermic and Exothermic Reaction

If you still do not know or have doubts about the differences between endothermic and exothermic reaction.

Endothermic Reaction

An endothermic reaction is one that requires or needs energy. This energy is supplied from the surroundings and the amount supplied from it may vary.

One of the most common examples of these reactions is photosynthesis, in which plants take energy from sunlight and then convert water and carbon dioxide into oxygen and sugar.

Symbolic equation: A + energy-> D

In this type of reaction, the energy content of the reactants is lower than that of the products.

Examples:

  • Ice melting
  • Dissolution of ammonium nitrate in water

Exothermic Reaction

An exothermic reaction is just the opposite of that described above. In some types of exothermic processes, a certain amount of heat may initially be required to start the process. Once supplied, the system starts to produce heat on its own. All combustion reactions fall into this category.

Symbolic equation: A-> B + C + energy

In this case, the energy content of the products is greater than that of the reactants.

Examples:

  • Digestion of food
  • All combustion reactions (fires)
  • Addition of an alkali metal to water

Finally the key differences between endothermic and exothermic reactions are: Endothermic reactions require energy, while the exothermic releases it.
