Formaldehyde (HCHO) can be formed by oxidation of methane. The oxidation process takes place by air (71% mole N2, 21 mole % 02) which is provided 25% excess. Methane is provided at the rate of 70 mol/s. CH4 + 02 -> HCHO + H20 CH4 + 2 02 ---> CO2 +2H20 iii) Calculate the fractional yield of formaldehyde if the produced formaldehyde amount is 30 mol/s.
