← ScienceWhich outcome occurs when a catalyst deactivates because of fouling?
A)Increased activation energy for reactants✓
B)Shift in equilibrium towards less product
C)Surface area reduction halts reaction
D)Enhanced selectivity for side product
💡 Explanation
Increased activation energy results from Diffusion Limitation, because fouling blocks reactant access; therefore reactants require more energy to react rather than altering the equilibrium constant, because equilibrium is a thermodynamic rather than kinetic property.
