← ScienceWhich outcome occurs when high concentrations inhibit catalyst binding?
A)The reaction rate plateaus.✓
B)The reaction is thermodynamically favoured
C)Equilibrium constant increases drastically.
D)Activation energy decreases exponentially.
💡 Explanation
The reaction rate plateaus because high concentrations block active sites via Competitive Inhibition, impeding substrate binding and thus slowing the overall rate-limiting step. Therefore, we observe a plateau in reaction rate rather than any other thermodynamic or energetic impacts from the blocked active site.
