High oxygen coverage

Figure 3a. CO2 evolution from the reaction of a molecular beam of CO with oxygen predosed onto Rh(l 10) to a coverage of 0.7 monolayers at a crystal temperature of 540 K, showing low reactivity at high oxygen coverage.

The unique ability of silver to epoxidize ethylene lies in the fact that it adsorbs oxygen dissociatively, and that atomic oxygen formed at high oxygen coverage is weakly bound. The low activity of silver to activate C—H bonds is the key factor in the selectivity of epoxidation. 

The above results indicate that a relatively high oxygen coverage on platinum promotes NO(a) formation. At low temperatures, NO(a) leads to N2O via ...

At high oxygen coverage, H-like bond forms annihilating the electron cloud of the dipoles to the bonding orbits of the oxygen adsorbate.
