AP Chemistry
5.11 Catalysis
The catalytic removal of pollutant gases from automobile exhaust includes the reduction of nitrogen monoxide, \(\text{NO}(g)\), by carbon monoxide, \(\text{CO}(g)\), over a solid platinum catalyst, as represented by the following equation:
\[ 2\,\text{NO}(g) + 2\,\text{CO}(g) \xrightarrow{\text{Pt}(s)} \text{N}_2(g) + 2\,\text{CO}_2(g) \]
Which of the following correctly classifies the \(\text{Pt}(s)\) catalyst and describes the primary mechanism by which it accelerates the reaction?
\[ 2\,\text{NO}(g) + 2\,\text{CO}(g) \xrightarrow{\text{Pt}(s)} \text{N}_2(g) + 2\,\text{CO}_2(g) \]
Which of the following correctly classifies the \(\text{Pt}(s)\) catalyst and describes the primary mechanism by which it accelerates the reaction?
