What is the difference between endothermic and exothermic reactions?

the major difference between endothermic and exothermic reactions is that an endothermic reaction is a process in which energy is acquired from its surroundings in the form of heat while an exothermic reaction is a process in which energy is released to the surroundings in the form of heat.

Endothermic Reactions

  1. A reaction in which heat is absorbed is called endothermic reaction.
  2. These are shown by the positive sign of Δ
  3. These are non-spontaneous reactions.
  4. Decomposition of reaction is endothermic reactions.

Exothermic Reactions

  1. A reaction in which heat is evolved is an exothermic reaction.
  2. These are shown by the negative sign of the Δ
  3. These are spontaneous reactions.
  4. Combustion reactions are exothermic reactions.
