← ScienceWhich consequence results when 'k' exceeds limits during catalysis?
A)Kinetic isotope effect is amplified
B)Diffusion limits observed rate constant✓
C)Equilibrium shifts towards product formation
D)Thermodynamic control increases selectivity
💡 Explanation
When 'k' is very high in catalysed reaction, the rate is no longer determined by the catalyst, due to encountering mass-transport constraints; therefore the observed rate constant reduces below expectations because diffusion limitation, rather than achieving full turnover.
