If a car’s catalytic converter fails, what is likely to increase in the car’s emissions?

  1. Carbon dioxide

  2. Methane

  3. Nitrogen

  4. Oxygen

The correct answer is: Carbon dioxide

When a catalytic converter fails, it can no longer effectively convert harmful gases into less harmful ones. As a result, the amount of pollutants such as carbon dioxide, carbon monoxide, and nitrogen oxides will increase in the car's emissions. Methane is not typically produced by gasoline-powered vehicles, and oxygen is a necessary component in the combustion process, so they are unlikely to be affected by a failed catalytic converter.
