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

• Finely-divided Iron

• Chromium

What is a reversible reaction?

• A reaction with oxidation and reduction

• A reaction with a forward and backward reaction

• A reaction with electron loss and gain

• A reaction that goes in reverse

How is nitrogen obtained for use in the Haber process?

• By the simple distillation of liquid air

• By the filtration of liquid air

• By the titration of liquid air

• By the fractional distillation of liquid air

The Haber process involves an exothermic reaction. What is the effect on the yield when the temperature is increased?

• More ammonia is produced

• Less ammonia is produced

• No change in ammonia produced

What would happen if the temperature of a Haber process is reduced to below  $450\degree C$  ? (Choose 2)

• Less ammonia would be produced

• The reaction would be faster

• The reaction would be slower

• More ammonia would be produced

What is the effect of increasing the pressure of a Haber process?

• Equilibrium shifts to the left, more ammonia is produced

• Equilibrium shifts to the left, less ammonia is produced

• Equilibrium shifts to the right, more ammonia is produced

• Equilibrium shifts to the right, less ammonia is produced

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
