WebJun 27, 2013 · The bottom line is that both endothermic and exothermic reactions involve the breaking of bonds, and both therefore require energy to get started. It makes sense that breaking bonds always takes energy. A chemical bond holds two atoms together. To break the bond, you have to fight against the bond, like stretching a rubber band until it snaps. WebAn 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. In an exothermic reaction, the change in enthalpy ( ΔH) will be negative.
