The dissociation energy of N2

Although agreement with experiment to within 1 kcal/mol is not achieved even with the most elaborate multireference CI (configuration interaction) wave functions and largest basis sets currently feasible, it is possible to obtain agreement to within about 2 kcal/mol, or 1 percent of the dissociation energy.

Dissociation Energy

It is the case of water electrolysis, and among the various technologies, high temperature steam electrolysis (so-called HTE or SOE for Solid Oxide Electrolysis) presents a major interest, since less electricity is required to dissociate water at high temperature, the remaining part of the required dissociation energy being added as heat, available at a lower price level.

Bond Energy vs. Bond Dissociation Energy vs. Stability

Jan 29, 2014Bond dissociation energy is DIFFERENT from bond energy unless we are talking about diatomic molecules. Bond dissociation energy is for individual bonds while bond energy is for AVG of all bond dissociation energies in the molecule. I think you are confused with potential energy vs bond energy. Potential energy is the one that makes bond less

An illustration describing the bond dissociation enthalpy of a Cl 2 is provided below. As discussed earlier, in the case of diatomic molecules, the bond dissociation enthalpy is equal to the bond energy. This is because bond energy is the average value of all the bond dissociation enthalpies of all bonds of the same type in a molecule.

what is bond dissociation energy?

Mar 21, 2006Best Answer: In chemistry, bond dissociation is a process in which a specific bond is cleaved by homolysis. Bond dissociation is an endothermic process, and energy that is necessary to the process is called bond dissociation energy. Note that following dissociation, if new bonds are formed at lower enthalpy, then there is a net loss of energy, and thus an overall exothermic process.

Bond Dissociation Energy

The bond dissociation energy is the energy required—an endothermic process—to break a bond and form two atomic or molecular fragments, each with one electron of the original shared pair. Thus, a very stable bond has a large bond dissociation energy—more energy must be added to cleave the bond.
