ANTONII [103]

Energy is transmitted to the surrounding in an exothermic reaction and this can be understood with the energy diagram of exothermic reaction attached with the answer.

<h3>What is an Exothermic Reaction ?</h3>

When a chemical reaction happens, energy is transferred to or from the surroundings.

When energy is transferred to the surroundings, this is called an exothermic reaction, and the temperature of the surroundings increases.

ΔH value negative –> energy released –> exothermic reaction

This happens because the reactants are at the higher energy state as compared to the products and therefore heat is liberated in the atmosphere to match the difference and therefore heat content in the surroundings increases.

The energy diagram for the exothermic reaction is attached with this answer.
