Gaseous ammonia is injected into the exhaust stream of a coalburning power plant to reduce the pollutant NO to N₂ according to the reaction:

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 22.4 torr. What should be the flow rate of ammonia delivered at 755 torr and 298 K into the stream to react completely with the NO if the ammonia is 65.2% pure (by volume)?
