← ScienceWhich consequence decreases catalyst efficiency due to rapid thermal fluctuations?
A)Increased reactant desorption rate constant✓
B)Decreased product adsorption affinity
C)Lowered activation energy threshold
D)Enhanced surface intermediate stabilization
💡 Explanation
An increased desorption rate reduces catalyst availability because the **Arrhenius equation** shows thermal fluctuations dramatically affect the rate constant, therefore products leave rapidly, rather than allowing further surface reactions improving yield .
