One Process for Hydrogen Production Is Called "Steam Reforming", in Which

Short Answer

One process for hydrogen production is called "steam reforming", in which hydrocarbons react with water to give hydrogen and CO. The equation of reaction for reforming methane is written below.
CH_{4 (g)} + H₂O _(g) $\rightarrow$ CO _(g) + 3 H_{2 (g)}
What is the free energy change, $\Delta$ G, for reforming methane at 298^oK when the partial pressure of the products is 5.0 x 10^-5 atm and the partial pressure of the reactants is 1.0 atm?
