Ammonia

Question 1

How is ammonia made

Answer 1

Industrially by reacting nitrogen with hydrogen in the haber process
it is a reversible reaction

Question 2

What is yield

Answer 2

Amount it a product made in a reaction

Usually expressed as %

Question 3

What does the yield of ammonia produced by the haber process depend on

Answer 3

Temp and pressure of reaction

Question 4

What is ammonia

Answer 4

An important compound in the manufacture of fertiliser and other chemicals

Question 5

What happens when lowering temp of haber process

Answer 5

Slows down rate of reaction

Takes longer for ammonia to be produced

Question 6

What is haber compromise

Answer 6

Highest yield of ammonia is theoretically produced by using a low temp and high pressure

Question 7

How do u provide a high yield of ammonia but with a fast rate of reaction

Answer 7

Carried out at 450 C and 200 atmospheres

Question 8

What costs are involved in industrial production of ammonia

Answer 8

Raw materials
Energy
Equipment
Wages

Question 9

What can be done to maximise production of ammonia

Answer 9

Iron catalyst to increase rate of reaction

Ammonia cooled, liquified and then removed as it is produced
