← ScienceWhich consequence results when ammonia production halts in Haber-Bosch process?
A)Hydrogen accumulation increases reactor pressure✓
B)Catalyst surface area decreases rapidly
C)Nitrogen concentration diminishes locally
D)Iron oxide forms within the reactor
💡 Explanation
Hydrogen has limited use without reacting to form ammonia; therefore, hydrogen's partial pressure rapidly elevates if *catalytic poisoning* halts ammonia product formation by blocking active sites. Consequently pressure increases; rather than Nitrogen diminishing if catalyst poisons accumulate.
