A gas mixture containing 1 mol/s H2, 2 mol/s CO and 1 mol/s CO2 is fed into a furnace at 1.5 bar. In addition to the species at the inlet, the outlet stream is measured to contain 0.40 mol/s of H2O vapor that has formed through chemical reaction. Assuming the reaction to produce water has reached equilibrium, estimate the temperature of the furnace. You may assume that Δhrxn = const and that no other species is produced in the chemical reaction.
