← ScienceWhich outcome occurs when the temperature of a Haber-Bosch process reactor increases beyond optimal conversion range?
A)Ammonia yield decreases from equilibrium shift✓
B)Catalyst poisoning from increased side reactions
C)Reactor vessel corrosion from hydrogen embrittlement
D)Explosive decomposition of unreacted gases
💡 Explanation
When reactor temperature increases, the equilibrium shifts according to Le Chatelier's principle because the forward reaction (N₂+3H₂ → 2NH₃) is exothermic, favoring reactants at higher temperatures. Therefore ammonia yield decreases, rather than poisoning, corrosion, or explosion, which require distinct chemical pathways and activation conditions.
