Car exhaust gases contain oxides of nitrogen. By what process are these oxides of nitrogen produced?
- ANitrogen and oxygen from the air react together at the high temperatures in the engine.
- BNitrogen and oxygen from the petrol react together in the car exhaust.
- CNitrogen from the petrol reacts with oxygen at the high temperatures in the engine.
- DNitrogen reacts with oxygen from the air in the catalytic converter.
