Which mechanism causes increased catalytic activity when transition metal atoms coordinate?

A)Orbital hybridization maximizes surface adsorption
B)Spin multiplicity decreases hindering reactivity
C)Core electron shielding becomes more stable
D)Phonon modes create excessive molecular vibration

💡 Explanation

Orbital hybridization concentrates electron density; this optimizes substrate binding through improved overlap of orbitals. Therefore this process drives catalysis, enhancing reactivity, rather than the alternatives that would hinder active site interactions.
