Methane is burned in reactor according to the reaction CH4(g)+2O2(g)CO2(g)+2H2O(v). The molar flow rate of methane in the feed is 1mol/s. The fractional conversion is 80%, and 70% excess O2 is fed to the reactor. Draw a fully labeled flow sheet, and use the extent of reaction method () to find the total molar flow rate in mol/s at the outlet
