← ScienceWhich consequence results when a platinum catalyst's surface decreases in effective area contacting reactants?
A)Reduced surface reaction rate✓
B)Increased activation energy barrier
C)Shifted equilibrium toward products
D)Elevated catalyst turnover frequency
💡 Explanation
Reduced catalyst surface area causes a reduced surface reaction rate because fewer reactant molecules can adsorb and react on the surface according to Langmuir-Hinshelwood mechanism; therefore, the reaction is slower rather than being altered energetically or shifting equilibrium.
