ynthesis gas, a mixture that includes the fuels carbon monoxide and molecular hydrogen, is used produce liquid hydrocarbons and methanol. It is made at pressures up to 100 atm by oxidation of methane followed by the steam re-forming and water-gas shift reactions. Because the is exothermic, temperatures reach 950 1100°C, and the conditions are such that the amounts of hydrogen, carbon monoxide, carbon dioxide, methane and water leaving the reactor are close to the equilibrium amounts for the steam re-forming...

Question 8 10 pts Methane gas reacts with water vapor to produce a mixture of carbon monoxide and hydrogen, according to the balanced equation below. CH4(8) + H2O(g) → CO(g) + 3H2(8) AH® for the reaction is +206.1 kJ/mol, while ASⓇ is +215 J/Komol. At what temperature (in °C) does this reaction become spontaneous?

Example At elevated temperatures, methane (CHA) reacts with water to produce hydrogen and carbon monoxide in what is known as a steam-reforming reaction: CH4(9)+H2O(g)= CO(g)+3H2(g) K= 2.4 x 10-4 at 900 K. Huge amounts of hydrogen are produced from natural gas in this way and are then used for the industrial synthesis of ammonia. If 1.2 x 10-2 mol of CH4, 8.0 x 10-3 mol of H20, 1.6 x 10-2 mol of CO, and 6.0 × 10-3 mol of H2...

Hydrogen and carbon dioxide can be used to produce carbon monoxide according to the water-gas shift reaction given by: H2 + CO2 = CO + H2O. If a reaction is set-up initially with n moles each of H2 and CO2 and none of either of the products, CO and H2O, and the variable x represents the fraction of H2 dissociated at equilibrium. Complete the following table in terms of n and x. H2 CO2 CO H2O Total moles Moles at...

"Synthesis gas" is a mixture of carbon monoxide and water vapor.
At high temperature synthesis gas will form carbon dioxide and
hydrogen, and in fact this reaction is one of the ways hydrogen is
made industrially. A chemical engineer studying this reaction fills
a flask at with of carbon monoxide gas and of water vapor. He then
raises the temperature considerably, and when the mixture has come
to equilibrium determines that it contains of carbon monoxide gas,
of water vapor...
