Worked Solution & Example Answer:A car engine burns fuel with insufficient air - HSC - SSCE Chemistry - Question 11 - 2002 - Paper 1
Step 1
Which substance would be emitted in higher levels?
Answer
When a car engine burns fuel with insufficient air, incomplete combustion occurs. This typically results in an increased emission of carbon monoxide (CO) compared to a properly balanced fuel-to-air ratio. In this state, carbon monoxide is produced due to the lack of sufficient oxygen for completing the combustion of carbon-based fuels. Therefore, the correct answer is:
(B) Carbon monoxide
