Which outcome raises reaction rate inside catalytic converters?

A)Increased reactant surface adsorption
B)Homogeneous catalyst deactivation occurs
C)Mean free path decreases
D)Gas pressure approaches ideal behavior

💡 Explanation

Increased reactant surface adsorption causes a rate increase, because the heterogeneous catalyst lowers the activation energy via enhanced contact; therefore, reaction rates increase, rather than decrease caused by deactivation or other changes.
