Haber process

THE HABER PROCESS ¯In the late 19th century, more food for thought was postulate to feed Europe and North Americas growing population. ¯The appurtenance of newton based fertilizer (NaNO3(s), NH3NO3(s)) increased crop yield. ¯Soon, thither was a high demand for the fertilizer itself. ¯In 1909, the German association BASF investigated the possibility of producing ammonia water 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 balance wheel mixture with ammonia - Optimum conditions: closed container, comm ensu 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 abut 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 diminish temperatures) ¯Using a catalyst eliminates the need for high temperatures allowing the equilibrium to move to the right at low temperatures ¯Today, we ar apply the Haber process to produce Brobdingnagian quantities of ammonia ¯Ammonia is apply to make explosives and fertilizers - dissolves in moisture premise in qualify (if the soil is acidic its converted into ammonia ion) and enters the nitrogen cycle where it is c onverted to nitrate ions by soil bacteria. N! itrate 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 prematurely UNDERSTANDING CONCEPTS 1. 1. Add N2(g) - this depart increase the reactant concentration. The system go away therefore try to balance the equilibrium...
