Which effect occurs when adding platinum catalyst to a catalytic converter with high exhaust gas flow rate?

A)Increased pollutant conversion efficiency
B)Reduced catalyst bed temperature
C)Decreased residence time of reactants
D)Enhanced backpressure on the engine

💡 Explanation

With high exhaust flow rate, adding a platinum catalyst accelerates the reaction kinetics, increasing reaction speed but reducing residence time of reactants on catalyst surface due to a large volume passing. Therefore decreased residence time result, rather than increased efficiency, lowered temperature, or reduced backpressure which needs lower pressure constraints.
