An equilibrium mixture of water vapor, methane, carbon monoxide, and hydrogen at 1400 K has the composition: [H2O] = 9.0 M, [CH4] = 8.0 M, [CO] = 2.0 M, [H2] = 6.0 M, for the equilibrium, H2O(g) + CH4(g) ↔ CO(g) +3H2(g). If the initial reaction mixture was composed only of water vapor and methane gas, what was the initial concentration of the methane in molarity units?

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 gas (a potential future fuel) can be formed by the reaction of methane with water according to the following equation: CH4(g)+H2O(g)?CO(g)+3H2(g) In a particular reaction, 25.5 L of methane gas (measured at a pressure of 736 torr and a temperature of 25 ?C) is mixed with 22.6 L of water vapor (measured at a pressure of 700 torrand a temperature of 125 ?C). The reaction produces 27.0 L of hydrogen gas measured at STP. What is the percent yield...

Syngas (CO+ H2) can be produced by reacting methane with water in the following reaction: CH4(g) + H2O(g) --> CO(g) + 3H2(g). If you want to maximize the syngas products at equilibrium, should you: (a) run the reaction at high or low temperature? (b) run the reaction at high or low total pressures? Briefly explain your answer.
