Which energetic consequence arises when antibonding molecular orbitals are populated during chemisorption?

💡 Explanation

When antibonding orbitals are populated, an increase in repulsive forces counteracts the attractive forces, weakening the overall bond because the antibonding character destabilizes the molecule-surface interaction. Therefore, a decrease in adsorption strength results, rather than enhanced vibrations, electron density increase, or dissociation which occur under different electronic configurations.
