WebAn example. In the manufacture of ammonia by the Haber Process, the rate of reaction between the hydrogen and the nitrogen is increased by the use of very high pressures. In fact, the main reason for using high pressures is to improve the percentage of ammonia in the equilibrium mixture, but there is a useful effect on rate of reaction as well. WebConcentration. The more concentrated a reaction mass is, the less solvent per ton of product will be used, leading to a reduction in both solvent inventory and reactor size. …
