← ScienceWhich outcome results when a catalytic metal nanoparticle's surface ligands destabilize frontier orbitals?
A)Increased activation energy barrier
B)Poisoning by substrate buildup
C)Enhanced reaction rate is achieved✓
D)Metal cluster sintering occurs rapidly
💡 Explanation
When surface ligands destabilize frontier orbitals, it promotes orbital mixing, increasing reactivity because this lowers the energy for the rate-determining transition state, therefore enhancing the reaction rate, rather than blocking active sites or increasing activation.
