WitrynaThe stronger the bond formed, the more energy is released during the bond formation process. In this particular reaction, because the newly formed bonds release more energy than was needed to break the … WitrynaAdd a comment. -1. The change in enthalpy is negative in an exothermic reaction because energy is "lost" through the reaction (because there is more energy on the products side than on the reactants side). Another way to think about this is by calculating the enthalpy before and after a reaction, for example - and this is a …
