One approach to using hydrocarbon fuels in a fuel cell is to “reform” the hydrocarbon to obtain hydrogen, which is then fed to the fuel cell. As a part of the analysis of such a procedure, consider the reaction CH4 + H2O ⇔ CO + 3H2. One kilomole each of methane and water are fed to a catalytic reformer. A mixture of CH4, H2O, H2, and CO exits in chemical equilibrium at 800 K, 100 kPa; determine the equilibrium composition of this mixture using an equilibrium constant of K = 0.0237.
