The reversible Haber reaction
The reversible Haber reaction
The Haber process reacts nitrogen with hydrogen to manufacture ammonia, an important starting material for fertilisers. All three substances are gases under the reaction conditions.
Step-by-step lessons on Edexcel GCSE Chemistry 6.3 Dynamic equilibria, covering 6.3.1 The Haber process as a reversible reaction, 6.3.2 Conditions and rate in industrial equilibria, and 6.3.3 Fertilisers and the preparation of ammonium sulfate. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
