In petrol engines of cars, oxides of nitrogen such as NO and NO$_2$ are produced. The car’s catalytic converter removes them from the exhaust gases by means of reactions. Which row shows how oxides of nitrogen are produced in a petrol engine, and a reaction taking place in the catalytic converter?
- Aby the reaction between nitrogen and oxygen from the air; $2\text{NO} + 2\text{CO} \rightarrow \text{N}_2 + 2\text{CO}_2$
- Bby the reaction between nitrogen and oxygen from the air; $2\text{NO} + 2\text{H}_2 \rightarrow \text{N}_2 + 2\text{H}_2\text{O}$
- Cby the reaction between nitrogen compounds in petrol and oxygen from the air; $2\text{NO} + 2\text{CO} \rightarrow \text{N}_2 + 2\text{CO}_2$
- Dby the reaction between nitrogen compounds in petrol and oxygen from the air; $2\text{NO} + 2\text{H}_2 \rightarrow \text{N}_2 + 2\text{H}_2\text{O}$
