Introduction: In this assignment I am going to explain two industries process that produce two different chemical products, also I am going to explain what Haber process is and contact process. And find out what are the advantage and disadvantage of Haber process and contact process. The Haber process: The Haber process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. * medium temperature (~500oC) * very high pressure (~250 atmospheres, ~351kPa) * A catalyst (a porous iron catalyst prepared by reducing magnetite, Fe3O4). Osmium is a much better catalyst for the reaction but is very expensive. This process produces an ammonia, NH3 (g), yield of approximately 10-20%. The Haber synthesis was developed into an industrial process by Carl Bosch. The reaction between nitrogen gas and hydrogen gas to produce ammonia gas is exothermic, releasing 92.4kJ/mol of energy...
