Endothermic Reaction- A reaction in which external heat is required to complete the reaction is called an endothermic reaction. Example- Melting of ice.
Exothermic Reaction- A reaction in which some amount of energy is released when the product formation is taking place, such types of reaction are called an exothermic reactions. Example- Burning of hydrocarbon.
The melting of ice is an example of an endothermic reaction.
