<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 while that of C in CO changed from +2 to +4 in
.
Thus, NO is acting as the oxidizing agent while CO is acting is the reducing agent.
