A prevalent form of toxic pollutant NOx formed in powerplant combustors is NO. Under favorable conditions, NO can be decomposed (“reduced”) via the following reaction:

At 1620 K, for a reaction rate expressed in gmol/L s and the amount of NO expressed in atmospheres, the reaction rate constant for this irreversible reaction is 0.0108 gmol/L s (atm)².
a. Assuming that NO is the only reactant, use the units of the rate constant to determine the order of this reaction in terms of NO.
b. If a reactor is designed to reduce NO at a rate of 0.056 gmol/min L at 1620 K, what partial pressure of NO is needed in the reactor?
