The Haber Process | GCSE Chemistry Practice

The Haber Process is used to manufacture ammonia, which is essential for making nitrogen-based fertilisers.

Why is a compromise temperature used in the Haber Process?

What is The Haber Process | Practice?

"An industrial process for producing ammonia from nitrogen and hydrogen by combining them under high pressure in the presence of an iron catalyst."

Question 1

What is produced in the Haber Process?

Question 2

Which catalyst is used in the Haber Process?

Question 3

What happens to the unreacted nitrogen and hydrogen in the Haber Process?

Haber Process Conditions

Raw materials: Nitrogen (from air) and Hydrogen (from natural gas).

Conditions: 450°C, 200 atmospheres, Iron catalyst.

Reversible reaction: N2 + 3H2 ⇌ 2NH3.

Ammonia is removed as a liquid; unreacted gases are recycled.

Exam Tip

Compromise Tip: 450°C is a compromise between a high yield (favoured by low temp) and a fast rate (favoured by high temp).

Want to improve faster?

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
