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.

Please answer the question with the steps... Thank you
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 + O2 --> HCHO +
H20
CH4 + 2 02 -> CO2
---->
+2H20
iii) Calculate the fractional yield of formaldehyde if
the produced formaldehyde amount is 30 mol/s.
