Question: Methane, CH4, is burned in a steady flow process with two different oxidizers: Case A: Pure oxygen, O2 and case B: A mixture of O2

Methane, CH4, is burned in a steady flow process with two different oxidizers: Case A: Pure oxygen, O2 and case B: A mixture of O2 + x Ar. The reactants are supplied at T0, P0 and the products for both cases should be at 1800 K. Find the required equivalence ratio in case (A) and the amount of Argon, x, for a stoichiometric ratio in case (B).
