Breaking chemical bonds is an endothermic process because it requires energy to be absorbed from the surroundings to overcome the attractive forces between atoms.
Bond Making (Energy Out): Forming new chemical bonds is an exothermic process because energy is released when atoms settle into a more stable, lower-energy state.
Net Result: A reaction is classified as exothermic overall if the energy released during the formation of new bonds (products) is greater than the energy required to break the original bonds (reactants). This excess energy is released to the surroundings, typically as heat.
