1.A reducing gas mixture consisting of 24 mol% CO, 4 mol% CO2, 60 mol% Hz and 12 mol% HzO is passed through a packed bed of wustite (FeO) pellets held at 1,100K. The pressure is maintained constant at 2.8atm. Assuming that the gas phase and the solids are in equilibrium, calculate the composition of the exit gas phase using the fkee energy minimisation method. The following data are given : C(s) ++O2(g) = CO(g) AC” = -1 12,880-86.51T,Jmol-‘ C(s)+ 02(g) = C02(g) AGO = -394,760 – 0,836T,Jmol-‘ Fe(s) + +O2(g) = FeO(s) AGO = -264,000 + 64.59T,Jmol-‘ H2(g) + $02(g) = H20(g) AGO = -247,390 +- 55.85T,Jmol-‘
