The combustion of methane in a feed contains 20% CH4, 60% O2 and 20% CO2 and a 90% conversion of the limiting reactant is achieved. Compute the molar composition of the product stream using (1) material balance on molecular species and (2) atomic balance. State the equilibrium expression of this reaction as well as how many moles of methane didn't react.
Must include balanced equation as well as full limiting reactant determination procedure
