Industrial reaction conditions for the production of ammonia is as shown below in the graph: Describe how the yield changes as the pressure is increased.

In the manufacture of ammonia by Haber's process, for all temperatures, as the pressure increases the yield of ammonia increases. This can be shown by the graph as given below:

Industrial reaction conditions for the production of ammonia is as shown below in the graph: A pressure of 200 atm is used during the process. Why does industry not use a much higher pressure to maximise yield?

A pressure of 200 atm is used is used during the process of manufacture of ammonia by Haber's process.The cost of building and maintaining equipment capable of withstanding high pressures during the manufacture of ammonia is expensive; improved safety practices must be employed when dealing with equipment at high pressure. Therefore, the industry does not use a much higher pressure to maximise the yield.

Industrial reaction conditions for the production of ammonia is as shown below in the graph: Explain with reference to the position of the equilibrium why increasing the pressure of this closed system favours the forward reaction.

In the manufacture of ammonia by Haber's process, the equilibrium reaction involves four moles of reactants and two moles of products; and an increase in pressure favours the side of the equilibrium with the smaller number of moles of gas in accordance with Le Chatelier's principle. Therefore, the forward reaction is favoured as the pressure is increased. N 2 g + 3 H 2 g ⇌ 2 NH 3 g
