We can calculate the necessary wavelength that is required to break bonds using the equation $\lambda=\hbar c/E.$ For example, light with a wavelength of about $\pu{241 nm}$ is needed to break the bonds of a $\ce{O2}$ molecule (assuming you know the bond …
Does exothermic make or break bonds
Did you know?
WebBond-breaking is an endothermic process.Energy is released when new bonds form. Bond-making is an exothermic process. Whether a reaction is endothermic or exothermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form. WebExothermic definition, noting or pertaining to a chemical change that is accompanied by a liberation of heat (opposed to endothermic). See more.
WebMar 14, 2024 · The process of breaking bonds required energy (so it is endothermic) and the process of forming a bond releases energy (so it is exothermic). The way I remember this is that the universe wants to make bonds, so it will be more inclined to form bonds and less inclined to break bonds because then that would use up energy. hope this help! WebJan 17, 2024 · A bond between two phosphate groups breaks, but one of the phosphate groups forms a new bond with the oxygen of water. Whether energy is released or taken up (whether the reaction is exothermic or endothermic) depends on the sum of the energies associated with breaking and making bonds in that reaction.
