← ScienceWhich consequence results when the reversible exothermic Haber-Bosch process in a closed vessel reaches equilibrium at high temperature?
A)Ammonia production rate stays unchanged
B)Nitrogen conversion decreases noticeably✓
C)Catalyst deactivation halts completely
D)Pressure inside vessel remains maximal
💡 Explanation
A higher temperature favors the reverse, endothermic reaction per Le Chatelier's principle, because the system opposes the heat change to restore equilibrium, therefore nitrogen conversion decreases noticeably, rather than remaining unchanged unlike lower temperatures.
