Please compute the answer of the following question
Question- 100 mol/min of a purge stream from a reactor's recycle stream contains 75 mol% propane and 20 mol% hydrogen, and 5 mol% nitrogen. It is burned with 20 mol% excess air. The fractional conversion of the propane is 90%, and of the hydrogen is 95%. 10 mole of carbon dioxide is formed for every mole of carbon monoxide.
