heat is absorbed in the reaction is called endothermic

Answer 2

Answer
========
===========


» 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.
