THE DISSOCIATION ENERGIES OF DIATOMIC MOLECULES OF THE TRANSITION ELEMENTS. PART I. NICKEL.

Abstract

The Ni2 molecule was shown to exist in the vapor phase over liquid nickel above 2000K. Using information derived from a combination of effusion and mass spectrometric techniques, the dissociation energy of Ni2 was calculated from the ratio of dimeric and monomeric nickel in equilibrium with liquid. The resulting value = 54.5 = 5 kcal. From the accepted value of the heat of sublimation of nickel and the dissociation energy of the dimer the heat of sublimation for the process 2 Ni (solid) = Ni2(gas) is, at 0 K, 146.9 = 7 kcal.
