Haber process

THE HABER PROCESS ¯In the late 19th century, more aliment was postulate to feed Europe and North Americas growing population. ¯The addendum 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 water water from atmospheric nitrogen, N2(g). An course later, Haber, a prof did it.

¯The observations were: - N2(g) and H2(g) form an correspondence mixture with ammonia - Optimum conditions: closed container, commensu rate thro ttle (iron oxide), a 600 ¢XC temperature, a 30 MPa pressure ¯This system is called the Haber Process ¯BASF brought the rights to the appendage 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 sparing ¯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 diminish temperatures) ¯Using a catalyst eliminates the need for high temperatures allowing the equilibrium to move to the right at low temperatures ¯Today, we argon apply the Haber process to produce Brobdingnagian quantities of ammonia ¯Ammonia is utilize to make explosives and fertilizers - dissolves in moisture premise in wangle (if the soil is acidic its converted into ammonia ion) and enters the nitrogen cps 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...
