Bond formation is exothermic

    • Thread Starter

    I was taught that the formation of bonds is an exothermic reaction, but what I don't quite get is why? Why heat is released when bonds are formed? I really like to know that. :confused:

    I think it's because when you break chemical bonds you need to supply energy(endothermic reaction) in order for the electrostatic force of attraction to be overcome so that new chemical bonds can be formed. When enough energy is eventually supplied the old chemical bonds release energy holding them together, giving out heat to the surroundings. I think that's why it's an exothermic reaction

    Analgous to two permanent magnets.

    Reactions always want to produce products that are energetically stable, therefore after you form the bond, energy will have to be released so as the final products can be more stable.

    Hope that helps.
