Question

Why is the exhaust gas of a car higher in concentration in carbon dioxide, and carbon monoxide, with respect to the normal atmosphere?

Answer 1

Because the car exhaust is enriched with carbon dioxide, and carbon monoxide, the which are already oxidation products.

Explanation:

`C_6H_14(l) + 19/2O_2(g) rarr 6CO_2(g) + 7H_2O(g)`.

The car exhaust contains gases that have already been combusted. Of course, some of the exhaust is carbon monoxide (the which is capable of further oxidation), but the exhaust gas would be deficient in combustible carbon.
