        Reaction CH₄+2H₂O=CO₂+4H₂ has been studied at 500° and atmospheric pressure.  Equilibrium was approached from both sides and the value of the constant found to be 0.037 (partial pressures being expressed in atmospheres) at 505°.  This is in excellent agreement with the value calculated from Lewis and Randall’s free-energy equations and thus supports in particular their equation for CH₄ in the low temperature region.  It is pointed out that the reactions CH₄+H₂O=CO+3H₂ and CO₂+H₂=CO+H₂O also are to be taken into account at higher temperatures.  Equilibrium constants at 500°, 600°, and 700° are given for reference.  Attention is called to the CH₄-steam reactions as a source of H₂ and of H₂-CO mixtures.
