For this assignment you will research one of the equilibrium systems below, or one approved by your instructor, and prepare a presentation describing the system. The Haber Process (or Haber-Bosch Process)

The Haber process is the process for converting nitrogen and hydrogen from natural gas into ammonia. Control & Click to follow link. The Haber Process PPT.ppt
Questions to Answer
Questions that should be answered by the content of your research project: 1. Describe the process you researched, including its uses in various industrial or health fields. I chose to research The Haber Process. It combines nitrogen from the air with hydrogen that comes from natural gas, into ammonia. The reaction is reversible and the production of ammonia is exothermic. 2. Who developed or discovered this process? When? What country was he or she from? (Provide this information if you can find it.) Fritz Haber, a German Chemist was the person who developed The Haber Process. He had developed it in 1905. Fritz Haber is from Germany. 3. Provide a short paragraph providing some historical background. Why is, or was, this an important chemical process? The Haber Process was developed at the time leading up to WWI. By 1914, German chemical engineer, Carl Bosch had helped Haber in converting the method into an industrial process. This was a very important chemical process because it produces ammonia which is used to make fertilizers, explosives, dyes, household cleaners, and nylon.

4. Write a balanced chemical equation for this reaction, including the energy term. Is it an endothermic or exothermic reaction? N2(g) + 3H2(g) 2NH3(g).The production of ammonia is exothermic. 5. Use Le Châtelier’s principle to explain the conditions that favor the forward reaction. The position of the equilibrium...
