Haber + Contact Process

Question 1

What does the haber process make ?
Equation?
Conditions ?
Where do we get nitrogen from ?
Where do we hydrogen ?

Answer 1

• Ammonia
• reversible reaction
• N2 + 3H2 <—> 2NH3) all gases
• Temp= 450 degrees , pressure = 200 atm/ 20000kpa , iron catalyst
• N2 fractional distillation of oxygen
  H2 natural gas

Question 2

What does the contact process make ?
Equations of all 4 steps ?
Conditions?
Sources of sulfur ?

Answer 2

Makes Sulfuric acid
- S + O2 —>. SO2
- 2SO2 + O2 —> 2SO3(use of vandium 5 ixide )
- SO3 + H2SO4 —> H2S2O7(oleum)
- H2S2O7 + H2O —> 2H2SO4

Conditions
- 450 C , 2atm /200kpa (no gas so low pressure )
- Vanadium (V) oxide
