← ScienceWhich consequence results when electron shielding is compromised in a catalyst?
A)Increased catalytic reaction rate occurs✓
B)Decreased catalyst thermal stability occurs
C)Changes to Fermi level result
D)Reduced product selectivity observed
💡 Explanation
If electron shielding is compromised, the effective nuclear charge increases causing a smaller atomic radius due to increased positive charge attracting the electron orbitals via Coulomb attraction; therefore catalytic activity increases, rather than decreases in activity which would arise from orbital expansion.
