Which outcome occurs when a hydrogen atom approaches a catalyst containing a high density of partially filled d-orbitals?

A)Increased dissociation of molecular hydrogen
B)Hydrogen becomes almost totally inert
C)Destabilization of catalyst surface occurs
D)Spin decoherence affects orbital hybridization

💡 Explanation

Increased dissociation occurs because of orbital overlap; the partially filled d-orbitals of the catalyst interact with the hydrogen's s-orbital, weakening the H-H bond via induced electron localization effects. Therefore, dissociation increases rather than inertness because of this lowered activation energy.
