5 Differences between Endothermic and Exothermic reaction

We have already discussed different chemical reactions and what happens during chemical reactions. Endothermic and exothermic reactions are part of those chemical reactions.

Here we will discuss 5 differences between endothermic ad exothermic reactions.

Difference between exothermic and endothermic reaction

What is an endothermic reaction?

Those reactions in which energy in the form of heat, light or electricity is absorbed or gained by reactants to form products are called endothermic reactions.

What is an exothermic reaction?

Those reactions in which energy in the form of heat is released by reactants to form products are called exothermic reactions.

 

Difference between Exothermic and Endothermic reaction in tabular form

S.No.	Endothermic Reaction	Exothermic Reaction
1	Reactants absorb energy from surroundings.	Energy is released to the surroundings.
2	The temperature of the surroundings decreases.	The temperature of the surroundings increases.
3	Energy is absorbed in the form of heat, light or electricity.	Energy is liberated in the form of heat only.
4	The total amount of energy of reactants is greater than the total amount of energy of products.	The total amount of energy of reactants is lesser than the total energy of products.
5	Melting ice, photosynthesis, and evaporation of water are examples of endothermic reactions.	Burning wood and the reaction between acids and bases are examples of exothermic reactions.

 

So these are the main 5 differences between endothermic and exothermic reactions.
