Haber process

THE HABER PROCESS ¯In the late 19th century, more pabulum was postulate to feed Europe and North Americas growing population. ¯The amplification of newton based fertilizer (NaNO3(s), NH3NO3(s)) increased crop yield. ¯Soon, in that respect was a high demand for the fertilizer itself. ¯In 1909, the German association BASF investigated the possibility of producing ammonium hydroxide water from atmospheric nitrogen, N2(g). An year later, Haber, a prof did it.

¯The observations were: - N2(g) and H2(g) form an offset mixture with ammonium hydroxide - Optimum conditions: closed container, commensu rate throttle (iron oxide), a 600 ¢XC temperature, a 30 MPa pressure ¯This system is called the Haber Process ¯BASF brought the rights to the touch and built a plant producing 10 000 t ammonium hydroxide per year TEMPERATURE ¯At low temperatures, the reaction of N2(g) and H2(g) is not economical ¯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 argon using the Haber process to produce Brobdingnagian quantities of ammonia ¯Ammonia is apply to make explosives and fertilizers - dissolves in moisture premise in variegate (if the soil is acidic its converted into ammonia ion) and enters the nitrogen rhythm method of birth control where it is converted to nitr! ate 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 go forth therefore try to balance the equilibrium...
