Is bond formation endothermic or exothermic
WebStronger bonds, such as covalent bonds, require more energy to break and release more energy when formed than weaker bonds, such as hydrogen bonds. Overall, bond formation is an exothermic process, meaning that … Web3 jan. 2016 · Bond formation is an EXOTHERMIC process. Bond breaking (i.e. fission, cleavage) is an ENDOTHERMIC process. We recognize that the combustion of methane …
Is bond formation endothermic or exothermic
Did you know?
WebIf more energy is released in making bonds than is used in breaking bonds, the overall process is exothermic, and ∆H sol is negative. If more energy is used in breaking bonds than is released upon solute-solvent bond formation, then the overall process is endothermic, and ∆H sol is positive.
