Which outcome reduces the chemical reaction rate within an industrial catalytic converter?

A)Catalyst surface area reduction occurs
B)Increased flow rate of exhaust
C)Higher operating temperatures achieved
D)Enhanced mass transfer effectiveness shown

💡 Explanation

Reduced surface area decreases the reaction rate because fewer active sites exist for adsorption and reaction, impacting the effectiveness; therefore, catalytic activity declines, rather than increasing with higher flow or temperature. This constraint limits the mass action.
