← ScienceWhich risk increases when a catalyst loses surface?
A)Increased activation energy requirement✓
B)Decreased substrate diffusion efficiency
C)Greater reaction equilibrium constant
D)Reduced product inhibition effectiveness
💡 Explanation
When a catalyst loses reactive sites, surface area decreases, therefore fewer reactant molecules can be activated; catalytic activity thus decreases because the activation energy requirement cannot be effectively bypassed by induced dipole interactions like the London dispersion force within enzymes, rather than altering equilibrium.
