Haber process

THE HABER PROCESS ¯In the late 19th century, more diet was postulate to feed Europe and North Americas growing population. ¯The rise to power of newton based fertilizer (NaNO3(s), NH3NO3(s)) increased crop yield. ¯Soon, on that point was a high demand for the fertilizer itself. ¯In 1909, the German association BASF investigated the possibility of producing ammonia water water from atmospheric nitrogen, N2(g). An socio-economic class later, Haber, a prof did it.

¯The observations were: - N2(g) and H2(g) form an remainder mixture with ammonia - Optimum conditions: closed container, commensu rate throttle (iron oxide), a 6 00 ¢XC temperature, a 30 MPa pressure ¯This system is called the Haber Process ¯BASF brought the rights to the demonstrate and built a plant producing 10 000 t ammonia per year TEMPERATURE ¯At low temperatures, the reaction of N2(g) and H2(g) is not efficient ¯Adding modify increases the rate of reaction ¯The higher the temperature, the lower the ammonia yield ¯Haber had to balance the rate of a reaction (increased by increasing temperature) against the equilibrium of the reaction (pushed to the right by fall temperatures) ¯Using a catalyst eliminates the need for high temperatures allowing the equilibrium to move to the right at low temperatures ¯Today, we ar victimisation the Haber process to produce Brobdingnagian quantities of ammonia ¯Ammonia is apply to make explosives and fertilizers - dissolves in moisture premise in alter (if the soil is acidic its converted into ammonia ion) and enters the nitrogen vibration where it is converted to nitrate ions by soil bacteria. Nitrate ions are absorbed! by plants through grow and used in proteins, chlorophyll and nucleic acids ¯Without nitrogen, the plants produce yellow leafs which beat the plant to dies untimely UNDERSTANDING CONCEPTS 1. 1. Add N2(g) - this depart increase the reactant concentration. The system allow for therefore try to balance the equilibrium...
