← ScienceWhich effect occurs when platinum catalysts reach equilibrium?
A)Reaction rate plateau✓
B)Increased side product formation
C)Enhanced substrate selectivity
D)Decreased catalyst surface area
💡 Explanation
Reaction rates reach a plateau because adsorption-desorption processes on the catalyst surface achieve a steady state, resulting in no net change from the dynamic equilibrium, therefore the catalytic activity stabilizes rather than showing continued exponential rate increases or declines.
