← ScienceWhich rate-dependent outcome arises when nitrogen fixation catalysts degrade?
A)Ammonia production rate decreases sharply✓
B)Catalyst surface area dramatically increases
C)Reaction equilibrium shifts towards reactants
D)Activation energy is significantly reduced
💡 Explanation
As catalyst active sites degrade, the reaction rate slows because the overall Turnover Frequency decreases; therefore ammonia production falls, rather than a shift in the equilibrium caused by concentration changes or activation energy lowering from remaining catalyst.
