AbstractThe article written by, Jayant M Modak, focuses on the production of ammonia through the Haber process, including a thorough explanation of the chemistry behind this process and background information of ammonia production.
Ammonia is used all over the globe as chemical fertilizers, explosives and as pharmaceutical and household cleaning products . However, what all these have in common is that they all require ammonia for their production. Due to the large demand for ammonia the Haber process was formed to produce the worlds second most produced chemical, ammonia. The equilibrium reaction of ammonia synthesis, requires the abundant nitrogen and hydrogen in the air, iron as a catalyst and 250-400 degrees Celsius of heat for the reaction to occur. This exothermic reaction releases 45.7 KJ/mol of energy at 298K or 25ÃÂ°c which is considerably high .
By using Le Chatelier's principle's and the collision theories, is known that the reaction for the synthesis of ammonia is most effective at low temperatures, high pressures and by using increased concentrations of reactants, which all shift...
