(b) In a process for the production of hydrogen required for the manufacture of ammonia, natural gas is to be reformed with steam according to the reactions: CH4+H2OCO+3H2.Kp(at1173K)=1.431013N2/m4CO+H2OCO2+H2,Kp(at1173K)=0.784 The natural gas is mixed with steam in the mole ratio 1CH4:5H2O and passed into a catalytic reactor which operates at a pressure of 3MN/m2(30 bar). The gases leave the reactor virtually at equilibrium at 1173K. Show that for every 1 mole of CH4 entering the reactor, 0.950 mole reacts, and 0.44 mole of CO2 formed. [12 marks]
