← ScienceWhich consequence results when a nickel catalyst surface area decreases in the Haber-Bosch process?
A)Lower ammonia production rate observed✓
B)Higher equilibrium constant achieved anyway
C)Increased process energy consumption shown
D)Reduced nitrogen activation energy seen
💡 Explanation
A smaller catalyst area reduces reaction rate because fewer active sites are available for the dissociative chemisorption of nitrogen via the Arrhenius equation. Consequently, ammonia production slows, rather than a shift in equilibrium or activation energy adjustment, therefore, output diminishes.
