Ammonia

Question 1

how is ammonia manufactured in bulk?

Answer 1

Haber process

Question 2

Haber Process optimal conditions
- temp
- pressure
- catalyst

Answer 2

• 450deg celc
• 200 atm
• iron

Question 3

Haber Process
Raw materials
Equation forming Ammonia

Answer 3

Hydrogen
Nitrogen

N2 + 3H2 ⇌ 2Nh3

they are all gaseous state.

Question 4

H____, N____

Haber Process
how to source for raw materials

Answer 4

Hydrogen: cracking of alkalines
Nitrogen: fractional distillation, liquefied air

Question 5

Define reversible chemical reaction

Answer 5

reaction
- products can change back 2 original reactant
- under suitable conditions

Question 6

How choose conditions + definition optimal conditions for Haber process

Answer 6

compromise btwn
- max yield
- speed of reaction

Optimal: produce good yield ammonia, acceptably fast rate reaction

Question 7

Decreasing temperature below optimal for Haber Process causes

Answer 7

Default
450degc

Advantage
better yield, ammonia

Disadvantage
slow down rate reaction

Question 8

Increasing pressure above optimal for Haber Process causes

Answer 8

Default
200atm

Advantage
Better yield ammonia

Disadvantage
Very expensive build plant

Question 9

Question 10

Displace ammonia in a chemistry lab

Answer 10

displacement o ammonia from its salts
- base/alkali + ammonium salt
- release ammonia gas

Question 11

How displace ammonia from soil

Answer 11

ammonium fertilisers (ammonium ion)
