← ScienceWhich outcome occurs to a catalyst surface when electron density mismatches substrate orbitals?
A)Reduced catalytic reaction efficiency✓
B)Increased catalyst surface area
C)Enhanced substrate adsorption strength
D)Improved thermal stability profile
💡 Explanation
A mismatch in electron density diminishes orbital overlap required for transition state formation; hence chemsorption. Poorer interaction diminishes turnover because the transition state isn't stabilised, rather than improved, therefore catalytic activity declines.
