Gaseous ammonia can be injected into the exhaust stream of a coal-burning power plant to reduce the pollutant NO to N2 according to the following reaction:
4 NH3(g) + 4 NO(g) + O2(g) → 4 N2(g) + 6 H2O(g)
Suppose that the exhaust stream of a power plant has a flow rate of 335 L/s at a temperature of 955 K, and that the exhaust contains a partial pressure of NO of 22.6 torr .
What should be the flow rate of ammonia delivered at 760 torr and 298 K into the stream to react completely with the NO if the ammonia is 65.2% pure (by volume)?
