← ScienceWhich process accelerates the Haber-Bosch reaction catalyst degradation?
A)Ammonia synthesis equilibrium establishment rate
B)Catalyst active site poisoning mechanism✓
C)Increased system temperature energy dispersion
D)Decreased reactant partial pressures mitigation
💡 Explanation
The catalyst's active sites become blocked by impurities, thus triggering the catalyst active site poisoning mechanism, leading to reduced efficiency because the surface area lowers; therefore, fewer reactions happen, rather than simply altering reaction energy, rates, or reactant pressures.
