How does high pressure increase percentage yield of ammonia?
Yes, this can be thermodynamically explained.
What effect does increasing pressure have on the yield of ammonia in the Haber process?
It increases the yield. 3 moles of hydrogen react with one mole of nitrogen to produce two moles of ammonia. As there is a REDUCTION in molecules, there will be a reduction in pressure. This is alsos an equilibrium reaction. So by Le Chetalier's principle, if we increase pressure, the system will react to reduce the pressure again. This can be done by producing more ammonia - in other words, an increase in product yield.
How would the yield of ethanol at equilibrium change if the temperature was increased?
If you raise the temperature, the endothermic reaction will increase to use up the extra heat, therefore producing less percentage yield of ethanol and more of ethene and steam.
Which is the best representation of the solvation of a sodium cation in water?
When sodium cations solvate into water, they break into Na+ and e- pairs. These are sodium and electrons. Liquid ammonia will also yield sodium ions.
What is the soil of the steppes like?
It contains a high amount of humus (7-15%), and high percentages of phosphoric acids, phosphorus and ammonia. This type of soil is very fertile and produces a high agricultural yield.
What happens to the yield of ammonia when the concentration of reactant is increased?
..
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.
What is the atom economy of ammonia?
The percentage yield of ammonia depends on the balance between the forward and backward reactions.
Nitrogen plus hydrogen yield ammonia?
N2 + 3h2 ---> 2nh3
What is the reaction called when nitrogen plus hydrogen yield ammonia?
Haber's process
How does high pressure increase percentage yield of ammonia?
Yes, this can be thermodynamically explained.
Can you prepare ammonia using calcium oxide and ammonium chloride?
Yes. Ammonium salts such as ammonium chloride will react with a strong base to yield ammonia.

How will a change in pressure and concentration affect the yield of ammonia made?
Per the Haber process, increasing the pressure moves the equilibrium position to the right, increasing the yield.
What are the conditions used to make ammonia?
When Nitrogen and Hydrogen gases are mixed at 450 degrees Celsius and at a pressure of around 150 atmospheres, the best yield of Ammonia is produced.
Nitric acid plus ammonia?
Ammonia and nitric acid react to form ammonium nitrate. NH3 + HNO3 --> NH4NO3
How is the neutron yield of an AmBe neutron source facility increased?
Fission
