Formaldehyde is produced by the oxidation of methane in a reactor. The following two parallel reactions occur.
CH4+O2⟶HCHO+H2O
CH4+2O2⟶CO2+2H2O
Methane and oxygen are fed to the reactor. The product gases leaving the reactor include methane, oxygen, formaldehyde, carbon dioxide and water vapor.
60 mol s-1 of methane enters the reactor. The molar flowrate (in mol s-1) of CH4, O2 and CO2 leaving the reactor are 26, 2 and 4, respectively. The molar flowrate of oxygen entering the reactor is _______ mol s-1.
