Methane and oxygen react in the presence of a catalyst to form formaldehyde. In a parallel reaction, methane is oxidized to carbon dioxide and water. CH4+O2HCHO+H2OCH4+2O2CO2+2H2O The feed to the reactor contains equimolar amounts of methane and oxygen. Assume a basis of 100.0mol feed/s. a. How many degrees of freedom remain for the overall process? b. The fractional conversion of methane is 0.890 and the fractional yield of formaldehyde is 0.865mol HCHO/molCH4 fed. What is the composition of the output stream? mol%O2mol%HCHOmol%H2Omol%CO2mol%CH4 c. What is the selectivity ( molHCHO/molCO2 ) of the process? molHCHO/molCO2
