- Making Ammonia
- Raw Materials for Haber Process
- Hydrogen
- From natural gas or other sources
- Nitrogen
- From the air
- Hydrogen
- The process
- Purified gases pass over an Iron catalyst
- At a high temperature of about 450'C
- At a high pressure of 200 atmospheres
- On cooling, Ammonia liquefies and is removed
- The remaining hydrogen and nitrogen is recycled
- On cooling, Ammonia liquefies and is removed
- At a high pressure of 200 atmospheres
- At a high temperature of about 450'C
- Purified gases pass over an Iron catalyst
- Nitrogen+Hydrogen=Ammonia
- Equilibrium
- Equilibrium is reached when reactions occur at same rate in each direction
- In a REVERSIBLE reaction in a CLOSED system
- Relative amounts of all reacting substances at equilibrium depend on the cnditions of the reaction
- If temperature increases
- Yield from ENDOthermic reaction increases and yield of EXOthermic decreases
- If pressure increases (In Gaseous Reactions)
- Favours the reaction that produces least number of molecules
- If temperature increases
- Equilibrium is reached when reactions occur at same rate in each direction
