Question
the federal new source performance standards for new coal-fired power plants require that the emissions of nitrogen oxides be less than 0.7 lb nitrogen oxides per million BTU of coal burned. These are to be computed based on all the nitrogen oxides being in the form of NO2. If aplant emits 0.4 lb. of NO and 0.1 lb. of NO2 per million BTU, What is the nitrogen oxide emission, reported as NO2? the federal new source performance standards for new coal-fired power plants require that the emissions of nitrogen oxides be less than 0.7 lb nitrogen oxides per million BTU of coal burned.

These are to be computed based on all the nitrogen oxides being in the form of NO2. If aplant emits 0.4 lb. of NO and 0.1 lb. of NO2 per million BTU, What is the nitrogen oxide emission, reported as NO2?Explanation / Answer
NO+1/2O2------->NO2
molar mass of NO= 30, molar mass of NO2= 46
30 lb NO produces 46 lb NO2
0.4 lb produces 0.4*46/30 lb NO2=0.613 lb NO2
total of NO2 produced per million BTU= 0.613+0.1= 0.713 per millon BTU
