Select the best single answer. The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: CO(g) + H2O(g) ⇌ CO2(g) + H2(g) At a given temperature, Kp = 2.7. If 0.13 mol of CO, 0.56 mol of H2O, 0.62 mol of CO2, and 0.47 mol of H2 are put in a 2.0−L flask, in which direction does the reaction proceed? The reaction will proceed to the right OR the reaction is at...

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.
