- 250 degrees
- 400-450 degrees
- 200 degrees
- 300-450 degrees
7. Why are optimum conditions not used?
- Very cheap to maintain but very expensive equipment.
- Can Cause 1000 explosions per minute.
- Very expensive to maintain and the equipment is very expensive.
- Earth's atmosphere cannot withstand them.

- Low yield.
- Small amount of oxygen needed.
10. What is an advantage to high pressure? (In The Haber Process)
- Increases yield.
- Decreases amount of nitrogen.
- Decreases temperature.
- Decreases yield.

- Nitrogen and hydrogen.
- Carbon Dioxide and Hydrogen
- Oxygen, nitrogen and hydrogen.
12. Why are fertilisers important?
- They make the plants for colourful and appealing.
- They help produce enough food for the growing world population.
- They help to produce healthier plants.
- They help kill any unwanted weeds.
13. What is an advantage to low temperature? (In The Haber Process)
- Helps keep nitrogen for longer.
- Increases the yield
- Decreases the waste
- Decreases the yield
14. What happens to the reactant gases that are not used up? (In The Haber Process)
- Recycled.
- Buried under ground
- Used to make fireworks
- Left
15. What are the compromised conditions in The Haber Process?
- Temperature= 610 degrees, Pressure = 300 atmosphere, catalyst of glass.
