The Haber process is basically converting Nitrogen and Hydrogen into ammonia. The equation is N2 + 3H2 -------> 2NH3 but it is an equilibrium. By Le Chetalier's principle if we apply pressure the system will try to counteract that by trying to lower pressure and to do this it needs to form product because there are 4 molecules of reactants and only two of product so the pressure is lower when there are fewer molecules. High Pressure thus favors high yields and hence good productivity and profitability.

How do you generate enough pressure to make ammonia?
We make ammonia by haber process. There must be a high pressure.
What is the best conditions for the haber process?
for maximum yield- low temperatures and high pressure, for maximum rate - high temperatures, high pressure and a catalyst.
How is ammonia liquified?
Ammonia is made by haber process. We can turn it to liquid by high pressure and low temperature.
Why is high pressure an important part of the oil extraction process?
High pressure is an important part of the oil extraction process because it squeezes the oil out of places that are hard to access.
How does pressure affect the haber?
The Haber process is a method of making ammonia from Hydrogen and Nitrogen N2 (g) + 3 H2 (g) 2 NH3 (g) An increase in pressure will disturb the system from equilibrium and the system will attempt to recover from this by counteracting the increase in pressure. To counteract the increase in pressure the system will favour the process that gives the least number of molecules (thus lowering pressure). as we can see above we have 4 moles of reactants for 2 moles of products in the equation. This means that an increase in pressure will cause an increase in the yield of ammonia. This reaction is also exothermic, so it would be correct to assume from a purely theoretical viewpoint that low temperature and high pressure would be best for this reaction. However the catalyst that is used in this reaction needs a temperature of around 450 degrees celsius to work, which is why this reaction is carried out at high temperature.

Why is the haber process not run at a high pressure?
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c

High pressure is an important part of the oil extraction process because it squeezes the oil out of places that are hard to access.
Why is the high yield is important on the haber process of manufacturing of ammonia?
The high yield means that a large percentage of chemicals used to make ammonia actually turns into ammonia instead of remaining unreacted.
Are nitrogen and hydrogen heated in Haber process?
Yes, they are heated in a ratio of 1:3. The temperature should be 400 degrees celcius. The pressure should be 2-3 atm.
Is the ammonia Haber Bosch process dangerous?
Working with gases (especially hydrogen and ammonia) at high temperatures and pressures may be dangerous.
High yield on the haber process?
Yield in the Haber process can be maximised by using low temperatures (as the synthesis of ammonia is endothermic) and high pressures (as it promotes the forward reaction as more moles of gas are on the reactants side). However, low temperatures mean a slow reaction rate so compromised temperatures of 300 degrees celsius must be used.

Why high pressure not more than 200 atmosphere not used in ammonia production?
In ammonia production (also known as the Haber process) the companies use a high amount of atmospheres to move the equilibrium so as to increase the yield of ammonia. Increasing the yield of ammonia saves money. However, creating a high pressure environment is very expensive, and above a pressure of about 200 atmospheres, it would start costing the costing the companies more than they make. Therefore they keep the pressure low enough to maximise their profit.
