A gas mixture of methane and steam at atmospheric pressure and 500C is fed to a reactor, where the following reactions occur: CH4 + H20 CO + 3H2 and C +H2O CO2 + H2 The product stream leaves the reactor at 850C. Its composition (mole fractions) is: yco, = 0.0275 yco=0.1725 VH,0=0.1725 YH, =0.6275 Determine the quantity of heat added to the reactor per mole of produet gas.
