Harber

Question 1

How is ammonia produced

Answer 1

Harber process

Question 2

Where does nitrogen come from

Answer 2

Air

Question 3

Where does hydrogen come from

Answer 3

Reacting methane with steam

Question 4

Conditions harber process

Answer 4

200 atm
450 degrees
Iron catalyst

Question 5

How do we get 450 degrees

Answer 5

It is a comprises temperature
Reaction Exothermic - we want cool temperature but reaction is slow
Trade between rate of reaction and equilibrium

Question 6

How do be decide pressure harber process

Answer 6

We want high temperature to favour right hand side

Question 7

Problem with high temp in harber process

Answer 7

Expensive and lowers yield

Question 8

What are fertiliser used

Answer 8

Grow larger and faster

Question 9

How to we get nitrogen in NPK fertiliser

Answer 9

Ammonia from haber process
Use ammonia to make nitric acid
React nitric acid with ammonia
To get ammonia nitrate

Question 10

How do get potassium for NPK fertiliser

Answer 10

Potassium chloride
Potassium Sulfate
Mined then Süd- directly

Question 11

Phosphate + nitric acid

Answer 11

Phosphoric acid and calcium nitrate
Neutralise phosphoric acid with ammonia
To get ammonia phosphate

Question 12

Phosphate rock + sulphuric acid

Answer 12

Calcium phosphate
Calcium Sulfate
Single super phosphate

Question 13

Phosphate rock + Phosphoric acid

Answer 13

Triple Superphosphate

Question 14

Ammonia + nitric acid is which type of reaction

Answer 14

Neutralisation

Question 15

School lab vs industrial ammonia

Answer 15

Dilute vs concentrate
Water bath vs uses earlier Exothermic reaction
Small amount vs large amount

Question 16

Mixture of gases in the reactor cool in the condenser suggest why ammonia condensers but the other gases do not

Answer 16

Ammonia has a high boiling point
