An exothermic reaction is a chemical reaction that releases energy through light or heat.

Answer 2

Exothermic Reaction :-

★An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.

★Expressed in a chemical equation: reactants → products + energy.

★If the energy produced in an exothermic reaction is released as heat, it results in a rise in temperature

Examples :-

• Combustion of fuels such as wood, coal and oil petroleum.

• Thermite reaction.

• Reaction of alkali metals and other highly electropositive metals with water.

• Condensation of rain from water vapor.
