Nitrogen oxide, NO, is produced inside the engine of petrol-powered cars. One component of petrol is octane, $\text{C}_8\text{H}_{18}$. Catalytic converters remove nitrogen oxide from exhaust fumes. Which row shows the reactants that form nitrogen oxide and a reaction that removes it in a catalytic converter?
- Aoctane + one gas found in air; $2\text{NO} + 2\text{CO} \rightarrow \text{N}_2 + 2\text{CO}_2$
- Boctane + one gas found in air; $\text{NO} + \text{CO}_2 \rightarrow \text{NO}_2 + \text{CO}$
- Ctwo gases found in air; $2\text{NO} + 2\text{CO} \rightarrow \text{N}_2 + 2\text{CO}_2$
- Dtwo gases found in air; $\text{NO} + \text{CO}_2 \rightarrow \text{NO}_2 + \text{CO}$
