Write the overall reaction equation of steam methane reforming. b. Calculate the overall Keq of steam methane reforming (both steps combined). c. Methane is a fossil fuel product that is largely obtained through fracking processes in the US. Alternatively, the Sabatier reaction is the synthesis of methane using CO2 and H₂: CO₂(g) + 4H2(g) CH4(g) + 2H₂O(g) The Sabatier reaction represents a fossil fuel-free pathway to obtain methane. Calculate the overall Keq for the Sabatier reaction.

Question
5. It is estimated that the synthesis of ammonia requires up to 1% of the world's energy production. If you think about all the things that require energy around us, 1% of world energy is a huge amount to dedicate to a single process. This energy is not actually used in the NH3 synthesis reaction shown in part 1, but required for the steam methane reforming reaction that produces H₂(g) (an essential ingredient in the Haber Bosch process). The steam methane reforming is the combination of two reactions: Step 1 Reforming reaction: CH4(g) + H₂O(g) ⇒ CO(g) + 3H₂(g) K₁ = 0.981 Step 2 Water-Gas Shift reaction: CO(g) + H₂O(g) — CO₂(g) + H₂(g) K₂= 1.04 a. Write the overall reaction equation of steam methane reforming. b. Calculate the overall Keq of steam methane reforming (both steps combined). c. Methane is a fossil fuel product that is largely obtained through fracking processes in the US. Alternatively, the Sabatier reaction is the synthesis of methane using CO2 and H₂: CO₂(g) + 4H₂(g) → CH4(g) + 2H₂O(g) The Sabatier reaction represents a fossil fuel-free pathway to obtain methane.
