← ScienceWhich outcome occurs when catalyst active sites saturate?
A)Reaction rate reaches maximum value✓
B)Activation energy exponentially increases
C)Equilibrium shifts against product bias
D)Rate constant diminishes toward zero
💡 Explanation
The reaction rate reaches a maximum because active sites being occupied prevents further substrate binding despite an increased reactant concentration. Therefore, additional increases in substrate concentration will not increase the reaction rate, rather than influencing kinetic equilibrium.
