← ScienceWhich outcome occurs when iron catalyst surface area decreases during Haber-Bosch process?
A)Ammonia production rate decreases✓
B)Equilibrium shifts towards reactants
C)Nitrogen conversion rate increases
D)Hydrogen partial pressure equilibrium rises
💡 Explanation
Decreasing catalyst area reduces active sites, therefore lowering overall reaction rate because adsorption's **Langmuir isotherm** impacts surface activity proportional to area. Equilibrium does not shift under new surface area, rather than favoring reverse due solely surface area impacting equilibrium constants.
