Web22 dec. 2004 · Earlier formulas for the electron‐pair bonding energies of methane, and radicals derivable from methane, are combined with recent data on the energy levels of the carbon atom, the heat of sublimation of carbon, the energy for removal of the first hydrogen, and the dissociation energy of CH to obtain the energies of CH 3 and CH 2.A … WebThe 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.
Webdissociation was in its pressure-dependent region. Estimates were also made of the rate constant for the reverse of [I] and showed fair agreement with recent experimental measurements. C.-J.
