When producing ammonia, there is not a 100% change from reactants into products. In fact, around half of the reactants will change into ammonia, and then equilibria is reached and the amount of ammonia will stay the same.
Increasing the pressure shifts the equilibria, so that more ammonia is produced when an equilibria is reached, making the process more efficient.
Hypothetical example:
1 litre of reactants (normal pressure) -----> 0.5 litre reactants and 0.5 litre ammonia
1 litre of reactants (high pressure) -------> 0.2 litre reactants and 0.8 litre ammonia
Increasing the pressure for the Haber process when producing ammonia can increase the percentage yield by shifting the equilibrium towards the formation of ammonia, as predicted by Le Chatelier's principle. This is because ammonia is produced when the system is under high pressure, promoting the forward reaction.
The Haber process is used to produce ammonia under conditions of high pressure (150-200 atm) and high temperature (400-500°C) over an iron catalyst. It requires a careful balance of temperature, pressure, and catalyst to optimize ammonia production.
The reaction between nitrogen gas and hydrogen gas under high pressure and temperature forms ammonia through a process called Haber process. Ammonia is a vital industrial chemical used in the production of fertilizers and various other products.
Hydrogen and nitrogen react to form ammonia (NH3) in the presence of a catalyst at high temperature and pressure.
When the gases leave the reactor they are hot and at a very high pressure. Ammonia is easily liquefied under pressure as long as it isn't too hot, and so the temperature of the mixture is lowered enough for the ammonia to turn to a liquid. The nitrogen and hydrogen remain as gases even under these high pressures, and can be recycled. Another way is to add the water to the mixture (or pass the mixture from cold water) Ammonia is highly soluble in water but other two gases are not.
The process for making ammonia is called the Haber-Bosch process. This involves combining nitrogen and hydrogen gases under high pressure and temperature in the presence of a catalyst to produce ammonia.
Ammonia is liquified by subjecting it to high pressure, typically around 8-10 atmospheres, and low temperatures of -33°C. This combination of pressure and temperature causes the ammonia gas to condense into a liquid state.

Ammonia is typically produced through the Haber-Bosch process, where nitrogen and hydrogen gases are reacted under high pressure (around 200 atm) and high temperature (400-500°C) in the presence of an iron catalyst. This process helps facilitate the formation of ammonia.
When hydrogen reacts with nitrogen under the necessary conditions of high temperature and pressure, they can combine to form ammonia (NH3) through a process called Haber-Bosch synthesis. This reaction is important in industrial production of ammonia, a key component in fertilizer production.
Water freezes faster than ammonia because water has a higher freezing point (0°C) compared to ammonia (-77.7°C). This means that water can freeze at a higher temperature, making the freezing process faster.
The temperature varies with its pressure. If pressure high the condensing temperature also high. please be more specific, can someone please provide more specifics to this?
No. Ammonia is a gas at room temperature..
Ammonia can exist as both a liquid and a gas depending on its temperature and pressure. At room temperature, ammonia is a gas, but it can be liquefied under high pressure or low temperature conditions.
450 degrees celcius at 150 atmospheres of pressure, plus an iron catalyst to speed up the reaction. These conditions are used becauase they produce the optimum amount of yield of ammonia at the cheapest rate.
No, gaseous ammonia is not a solid. Ammonia at room temperature and pressure exists in the gaseous state. It turns into a solid only at very low temperatures and high pressures.
