← ScienceWhich outcome results when a catalyst saturates in solution?
A)Reaction rate plateaus despite substrate increase✓
B)Activation energy decreases uncontrollably
C)Equilibrium constant exponentially increases
D)Reverse reaction rate becomes significantly greater
💡 Explanation
The reaction rate plateaus as the catalyst is rate-limiting because all active sites are occupied, therefore rate becomes independent of substrate concentration at high excesses rather than activation energy changing significantly or shifting equilibrium.
