Ammonia (NH3) is one chemical that has been touted as a potential medium for storing hydrogen for vehicles. Using a ruthenium catalyst the ammonia decomposes completely into hydrogen and another diatomic inert gas. For an on demand supply the reaction is carried out at 177C at standard pressure of 800kPa, constantly filling a 200L tank. The vehicle storage tank is pressurised to 2 atm at 25C. How many moles of ammonia would be required to refill the main tank to full capacity after a vehicle takes a 55L fill?

Synthesis gas, a mixture that includes the fuels CO and H₂,is used to produce liquid hydrocarbons and methanol. It is madeat pressures up to 100 atm by oxidation of methane followed bythe steam re-forming and water-gas shift reactions. Because theprocess is exothermic, temperatures reach 950–1100C, and theconditions are such that the amounts of H₂, CO, CO₂, CH₄, and H₂O leaving the reactor are close to the equilibrium amounts forthe steam re-forming and water-gas shift reactions:CH₄(g) +H₂O(g) ⇌CO(g)+ 3H₂(g) (steam re-forming)CO(g) +H₂O(g) ⇌CO₂(g)+ H₂g) (water-gas shift) (a) At 1000.°C, what are ΔG° and ΔH° for the steam re-formingreaction and for the water-gas shift reaction?
