"WebThe reaction is zero order in CO; thus n = 0. The rate law is: rate = k[NO2]2[CO]0 = k[NO2]2 Remember that a number raised to the zero power is equal to 1, thus [CO] 0 = 1, which is why the CO concentration term may be omitted from the rate law: the rate of reaction is solely dependent on the concentration of NO 2.
