Step 1
Describe how oxides of nitrogen are produced in a car engine.
Answer
Oxides of nitrogen (NOx) are produced in a car engine due to the high temperatures that occur during combustion. At these elevated temperatures, nitrogen from the air reacts with oxygen, leading to the formation of nitrogen oxides. The engine's combustion process provides the necessary conditions for these reactions to take place, allowing nitrogen and oxygen to bond.
