Abstract
The bond-order conservation principle is shown to be rigorously true within the valence-bond approxn. excluding inorg. terms. After a short discussion of Sustrorovich's adaptation of this method to chemisorption on metals, a new improved expression for the activation energy of dissocn. is derived, based on a transition-state model derived from extended Hueckel calcns. It appears to be essential to account for the weakening of the surface-surface metal bonds. New expressions for at. and mol. adsorption energies are derived. A major result of this work is a significant redn. in the activation energy for dissocn. due to loss of surface metal-metal atom bonding upon chemisorption
