Contextual Outline: 9.4 CHEMICAL MONITORING AND MANAGEMENT 9.4.2 ?????????????????? The intention of the Haber pick out for is to farm ammonium hydroxide. So to unsex the roughly ammonia we essential the equilibrium to be saced a good deal to the aright to get lots of ammonia. To do this we can do several(prenominal) things, the first base is to decrease the temperature of the system. Decreasing the temperature go out lowly that, due to Le Chateliers principal, the equilibrium entrust shift to the right to produce to a greater extent heat, to minimise the effect of the change, exactly in the process will produce more yield, more NH3. However in dot point 5 we precept that the lower the temperature the drawn-out the place of answer and so at low temperatures although the proportionality of NH3 produced to N2 and H2 produce is quite high, due to the poky chemical reaction enjoin at these temperatures, the rate that both products are produced is quite low. So in actuality not much NH3 is produced. to a fault the higher the pull the more yield, barely the higher the rack the slower the reaction rate, because the particles cant move around as much. Also high pressures make it harder to maintain the equipment. Fig. 52 The diagram below shows the reaction curves for alter factors. A change in temperature, also changes the rate of the reaction, which scales the represent along the time axis.

high med low temp tote up to Le Chateliers Principle, a change in temperature, volume, immersion or pressure will change the height of this. Fig. 53 8. beg off that the use of a catalyst will lower the reaction temperature requi red and identify the catalyst(s) utilize in! the Haber process The catalyst used is iron oxide. This lowers the activation temperature that is necessitate to start the reaction. 9. analyse the advert of increased pressure on the system involved in the Haber process Increased pressure on the system involved in the Haber process will put more stress on the pipes. The pipes will engage to be thicker to withstand the higher pressures....If you want to get a full essay, order it on our website: OrderEssay.net
