Heat is absorbed when hydrogen bonds break
Web22 oct. 2024 · The H-H bond energy is 436 kJ/mol. H + H → H 2 ΔH = -436 kJ/mol. It means 436 kJ/mol of heat is required to break the Avogadro’s number of H 2 molecules into individual atoms. Thus, bond energy per bond is 72.42 x 10 23 kJ/mol. This is obtained by dividing 436 by 6.02 x 10 23. As the bonding electron pair is equally shared between the … Web14 mar. 2024 · Breaking bonds will require energy since they are endothermic reactions whereas forming bonds will release energy since they are exothermic reactions. This is because when bonds are formed, the potential energy in the form of chemical energy is lowered, which causes energy to be released. Top Amy Huang Posts: 51 Joined: Tue Jan …
