The oxidation state of N changes from +2 to 0 while that of C changed from +2 to +4.

<h3>Oxidation and reduction</h3>

Oxidation is defined as an increase in oxidation number of the addition of oxygen while reduction is a decrease in oxidation number or removal of oxygen.

In the reaction shown by the equation, the oxidation number of N in NO changed from +2 to 0 in $N_2$ while that of C in CO changed from +2 to +4 in $CO_2$ .

Thus, NO is acting as the oxidizing agent while CO is acting is the reducing agent.
