level questions: The Haber Process

QuestionAnswer
What is the Haber Process Equation?Its: N₂ + 3H₂ ⇌ 2NH₃ [+ Heat]
How is the Nitrogen and Hydrogen Obtained?-Nitrogen can be gained from the Air [76% = Nitrogen] -Hydrogen can be gained from Hydrocarbons in Natural Gases or Crude Oil
What is the Ammonia used for?-Simply for Fertilisers
In the Haber Process, what are the Conditions used in Industry?-There is a Pressure of 200 atm [200MPa] -There is a Temperature of 450 Degrees -There is an Iron Catalyst present
Why is the Pressure, for the Haber Process, like that?-This is because the High Pressure shifts the Equilibrium Position to the side with the Least Amount of Moles, and here being the Ammonia -This means the overall Yield is Higher -Although, the reason why its only 200 atm, and not 1000 atm is because of Expense. It would be an absolutely Nightmare to have a Plant that can Withstand it, and then actually Fund it
Why is the Temperature, for the Haber Process, like that?-Increasing the Temperature would actually mean the Position of Equilibrium will go Against that, and go the Endothermic route making more Hydrogen and Nitrogen, which Isn't needed -However, Temperature also affects the Rate of Reaction, which means the Lower the Temperature, the Longer it Takes -450 Degrees is then a Compromise between the Yield and the Rate
Why is there a Iron Catalyst in the Haber Process?-The Catalyst doesn't affect the Equilibrium Position, but it does affect the Rate of Reaction -This means it allows the Temperature to be Lower, and therefore the Cost Decreases.
