The emission of NO2 by fossiI fuel combustion can be prevented by injecting gaseous urea into the combustion mixture. The urea reduces NO (which oxidizes in air to form NO2) according to the reaction:
2 CO(NH2)2(g) + 4 NO(g) + O2(g) → 4 N2(g) + 2 CO2(g) + 4 H2O(g)
Suppose that the exhaust stream of an automobile has a flow rate of 2.55 L/s at 655 K and contains a partial pressure of NO of 12.4 torr. What total mass of urea is necessary to react completely with the NO formed during 8.0 hours of driving?
