Bond energy is the amount of energy released when 1 mole of bonds are formed from the isolated atoms in the gaseous state or the amount of energy required to dissociate one mole of bonds present between the atoms in the gaseous molecules. It is represented by Δ b H or Δbond H. For diatomic molecules like H2, O2, N2, Cl2, HCl, HF etc. the bond energies are equal to their … [Read more...] about Bond Enthalpy
