The Haber Process

The Haber process is the name we give to the industrial production of

• Ammonia
• Salt
• Sodium Hydroxide
• Soap

Which of the following metals can be used to catalyse the synthesis of ammonia?

• Aluminium
• Iron
• Nickel
• Platinum

Ammonia is used for:
a) cleaning agent
b) fertiliser
c) explosive production
d) 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

Nitrogen for the Haber process is formed by 

• Fractional distillation of air
• Fractional distillation of crude oil
• Electrolysis of water
• Fixation of nitrogen by pea plants

Hydrogen for the Haber process is made from

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

Nitrogen + hydrogen −> ammonia is exothermic .  What will happen if we increase the temperature

• The reaction will slow down
• There will be no change in ammonia production
• More ammonia will be produced
• Less ammonia will be produced

If we increase the pressure, what will happen to the reaction

• It will slow down
• More ammonia will be produced
• Less ammonia will be produced
• Nothing will change

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
