Is breaking a chemical bond exothermic
Web1 apr. 2024 · $\begingroup$ Still, energy is not released when a bond is broken, even in an exothermic reaction. You need to separate two atoms which have an attractive force between them. That has to require energy. In an exothermic reaction, generally, more bonds form than break, so there is an energy surplus. $\endgroup$ –
