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

• Ammonia
• Salt
• Sodium Hydroxide
• Soap

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 + 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
