The emission of NO2 by fossil fuel combustion can be preventedby injecting gaseous urea into the combustion mixture. The ureareduces NO (which oxidizes in air to form NO2) according to thefollowing reaction:
2CO(NH2)2(g)+4NO(g)+O2(g)→4N2(g)+2CO2(g)+4H2O(g)
Suppose that the exhaust stream of an automobile has a flow rate of2.56 L/s at 672 K and contains a partial pressure of NO of 13.5torr .
a.) What total mass of urea is necessary to react completelywith the NO formed during 8.2 hours of driving?
