The following reaction occurs in a car’s catalytic converter.

2NO(g) + 2CO(g) mc026-1.jpg N2(g) + 2CO2(g)

Which answer best describes the reducing and oxidizing processes in this reaction?
NO and CO are both reducing agents.
NO and CO are both oxidizing agents.
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
The oxidation state of nitrogen in NO changes from 0 to +2, and the oxidation state of carbon in CO changes from +4 to +2 as the reaction proceeds.

Correct choice: "The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds."

Reason: N in NO is +2 and is reduced to 0 in N2 (so NO is the oxidizing agent). C in CO is +2 and is oxidized to +4 in CO2 (so CO is the reducing agent).
