Detailed explanation-1: -Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.

Detailed explanation-2: -What is an Exothermic Reaction? An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction.

Detailed explanation-3: -When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing a thermometer in the reaction mixture.

Detailed explanation-4: -What is an Endothermic Reaction? Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

Detailed explanation-5: -Hence, when a chemical change takes place with the release of heat energy, it is said to be an exothermic reaction.
