Petrol engines give rise to the primary pollutant nitrogen monoxide, $\text{NO}$, which is carried in exhaust gases. Which reaction in a catalytic converter lowers nitrogen monoxide emission?
- A$\text{NO}(g) + \text{CO}(g) \rightarrow \text{NO}_2(g) + \text{C}(s)$
- B$\text{NO}(g) + \text{CO}_2(g) \rightarrow \text{NO}_2(g) + \text{CO}(g)$
- C$2\text{NO}(g) + 2\text{CO}(g) \rightarrow \text{N}_2(g) + 2\text{CO}_2(g)$
- D$2\text{NO}(g) + \text{CO}_2(g) \rightarrow 2\text{NO}_2(g) + \text{C}(s)$
