← ScienceWhich outcome occurs when iron catalysts saturate reagents?
A)Reaction order becomes pseudo-zero-order✓
B)Heterogeneous inhibition reactions accelerate sharply
C)Equilibrium shifts maximizing activation energy
D)Catalyst solubility drastically reduces output rate
💡 Explanation
The outcome is pseudo-zero-order kinetics due to saturation. Reaction **rate-becomes** independent of substrate concentration **because** all catalytic sites occupied exhibit zero-order mechanism; **therefore**, rate changes minimally, **rather than** speeding dramatically through some inhibition or significantly reducing the catalyst's effects.
