A gas mixture of methane and steam at atmospheric pressure at 773.15K is fed to a reactor, where the following reactions occur:
CH4+H20->CO+3H2 and CO+H2O->CO2+H2
The product stream leaves the reactor at 1123.15K.
Its composition (mole fractions) is:
yCO2=.0275 yCO=.1725 yH2O=.1725 yH2=.6275
determine the quantity of heat added to the reactor per mole of product gas.
