Haber Process

The Haber process is the industrial process for making...

• Ammonia

• Sulfuric Acid

• Salts

What are the raw materials for the Haber process?

• Hydrogen and Oxygen

• Hydrogen and Nitrogen

• Water and Nitrogen

• Oxygen and Nitrogen

What are the optimum conditions for the Haber process?

•  $450\ atm$ and $200\degree C$  

•  $200\ atm$  and  $450\degree C$  

What is the catalyst used in the Haber process?

• Vanadium (V) Oxide

• Nickel

• Iron

• Chromium

How is nitrogen obtained for use in the Haber process?

• By the fractional distillation of liquid air

• By the filtration of liquid air

• By the titration of liquid air

Ammonia is used :

a) as a cleaning agent

b) in the manufacture of fertilisers

c) in explosives production

d) in soap production

• a and b

• b, c and d

• a, b and c

• c and d

Which equation represents the formation of ammonia

• N₂ + H₂ ₋> NH₃
• N + 3H ₋> NH₃
• N₂ + 3H₂ ₋> NH₃
• N₂ + 3H₂ ₋> 2NH₃

Hydrogen for the Haber process is made from

• Methane in natural gas
• Fractional distillation of air
• Fractional distillation of crude oil
• Electrolysis

Why aren't high pressures for the Haber process used in industry?

• Too expensive and dangerous
• Less ammonia is formed
• The reaction is too slow
• The catalyst is poisoned

What are the usual conditions of the Haber Process?

• 450'C, 550 atm, Iron Catalyst

• 100'C, 200 atm, Diamond Catalyst

• 450'C, 200 atm, Iron Catalyst

• -450'C, 250 atm, Iron Catalyst
