Injecting gaseous urea into the combustion mixture

Assignment Help Chemistry
Reference no: EM131436959

The emission of NO2 by fossil 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 this reaction:

2CO(NH2)2(g)+4NO(g)+O2(g)→4N2(g)+2CO2(g)+4H2O(g)

Assume that the exhaust stream of an automobile has a flow rate of 2.53 L/s at 658 K and contains a partial pressure of NO of 10.3 torr.

Part A

What total mass of urea is necessary to react completely with the NO formed during 7.8 hours of driving?

Express your answer using two significant figures.
