Question

what is meant by exothermic reaction and endothermic reaction ​

Answer 1

Answer.

⚫Exothermic reaction

◾If the total energy of the reactants is more than that of the products of the reaction then the reaction is exothermic in this case energy is released.

⚫Endothermic reaction

◾If the total energy of the reactants is less than that of the products of the reaction then the reaction is endothermic.Energy will be observed by the reactants to give rise to Products.

» Exothermic Reaction
===================

• Exo means "release"

Which release heat energy to environment is known as Exothermic Reaction.

• These are spontaneous reaction.

• In these products have less energy than reaction.

• Lightening of a candle is an example of Exothermic Reaction.

All combustion reaction are Endothermic Reaction.

===================================

» Endothermic Reaction
====================

• Endo means "absorb".

Which absorb heat energy from surrounding are known as Endothermic Reaction.

• These are non - spontaneous reaction.

• In these products have more energy than reaction.

• Melting of ice is an example of Endothermic Reaction.
