Which consequence results when excess reactant overwhelms catalyst sites?

A)Reaction exhibits saturation kinetics.
B)Catalyst undergoes phase transformation.
C)Activation energy exhibits redshift.
D)Equilibrium constant significantly increases.

💡 Explanation

The reaction displays saturation kinetics because zero order kinetics arise from substrate excess via Langmuir adsorption; therefore, the rate plateaus, rather than the catalyst changing phase, the activation weakening, or a non-existent impact on the final equilibrium.
