A reaction in which energy is released to the surroundings is called an exothermic reaction. In this type of reaction the enthalpy, or stored chemical energy, is lower for the products than the reactants. ... Because reactions release or absorb energy, they affect the temperature of their surroundings.

Answered by PlayerGuy

during a chemical reaction, there is a change in energy as-
1.new substances are formed in a chemical reaction
2.for this, old bonds are broken and new bonds are made between the atoms.
3.for such a process, energy may be required to make such bonds, or energy might be released when bonds are broken.
4.on this basis, with the amount of energy taken in or given out, the reaction is classified exothermic or endothermic.

hope it helps plz mark as brainliest
