ZERO ORDER REACTION
A reactant whose concentration does not affect the reaction rate is not included in the rate law. In effect, the concentration of such a reactant has the power 0. Thus [A] 0 = 1.
A zero order reaction is one whose rate is independent of concentration. For example, the rate law for the reaction at 200° C is
Here the rate does not depend on [CO], so this is not included in the rate law and the power of [CO] is understood to be zero. The reaction is zeroth order with respect to CO. The reaction is second order with respect to [NO2]. The overall reaction order is 2 + 0 = 2.
