← ScienceWhich outcome follows catalytic converter deactivation in automobiles?
A)Increased regulated pollutant emissions✓
B)Increased conversion of carbon dioxide
C)Decreased nitrogen oxides formation
D)Optimized engine combustion efficiency
💡 Explanation
Deactivation reduces the number of active sites, lowering activity because the rate of pollutant conversion decreases via surface adsorption, therefore regulated emissions increase rather than decreasing, in contrast to the desired function catalyst performs.
