← ScienceWhich risk substantially increases when the shape of hybridized atomic orbitals is distorted in a catalytic platinum nanoparticle?
A)Reduced activation energy barrier occurs
B)Loss of catalytic reaction selectivity✓
C)Increased metal-support sintering results
D)Improved resistance to surface fouling
💡 Explanation
Loss of selectivity occurs because the shape is distorted causing a change in orbital overlaps and therefore alters the binding affinity of specific reactants, rather than decreasing the activation energy which requires strong, selective adsorption.
