If the volume of the reaction vessel is decreased will the yield of ammonia increase or decrease and why?
If you decrease the volume of the of the reaction vessel, you will get a higher yield of ammonia.
This is because, decreasing the volume means the particles are more crammed in together and they will collide successfully more often and frequently. This causes a shift in the direction that produces more gas molecules. And since the balances equation for ammonia production is:
N2 + 3H2 ----> 2NH3
4 particles on the left, 2 on the right, meaning it will shift to the right, i.e. to the production of ammonia.
Hope this helps!

Why does the yield of ammonia at equllibrium increase as the temperature is decreased?
When the temperature is decreased, the reverse reaction (in this case, the decomposition of ammonia into nitrogen and hydrogen) is favored because it is an exothermic reaction. In response to the increased reverse reaction, the forward reaction (formation of ammonia from nitrogen and hydrogen) increases to re-establish equilibrium, ultimately leading to a higher yield of ammonia.
The production of ammonia from gaseous hydrogen and gaseous nitrogen will what at a higher temperature?
The production of ammonia from gaseous hydrogen and gaseous nitrogen will increase at a higher temperature. This is because the reaction is endothermic, meaning it requires heat to proceed. Higher temperatures provide the necessary energy for the reaction to occur more rapidly.
How would a decrease in temperature affect the yield of ammonia?
A decrease in temperature would decrease the yield of ammonia as the reaction to produce ammonia is exothermic, meaning it releases heat. At lower temperatures, the equilibrium shifts to favor the reactants, resulting in lower ammonia production.
How is ammonia separated in the Haber process?
In the Haber process, ammonia is separated from the unreacted nitrogen and hydrogen gases by compressing the reaction mixture. This causes ammonia, being a soluble gas, to liquefy and separate from the remaining gases. This process helps to increase the concentration of ammonia and improve the overall efficiency of the reaction.
Does temperature affect the production of ammonia from ammonia chloride?
Yes, temperature can affect the production of ammonia from ammonium chloride. Generally, higher temperatures can increase the rate of the reaction, leading to more ammonia production. However, excessively high temperatures can also cause decomposition of ammonia.

What will happen if a small amount of sodium hydroxide is added to a 0.1 M solution of ammonia?
The sodium hydroxide will react with ammonia to form a complex called sodamide and water. This reaction will increase the pH of the solution and result in the formation of a new compound.
The production of ammonia from gaseous hydrogen and gaseous nitrogen will what at a higher temperature?
The production of ammonia from gaseous hydrogen and gaseous nitrogen will increase at a higher temperature. This is because the reaction is endothermic, meaning it requires heat to proceed. Higher temperatures provide the necessary energy for the reaction to occur more rapidly.
The industrial production of amonia is described by the reaction?
The industrial production of ammonia involves the Haber-Bosch process, which combines nitrogen and hydrogen gases under high pressure and temperature in the presence of an iron catalyst to form ammonia. This reaction is reversible, and the yield of ammonia can be increased by using high pressure and low temperature. Ammonia is a key component in the production of fertilizers, explosives, and various chemicals.
What way will the reaction shift in a decrease in temperature for an endothermic reaction?
A reaction that absorbs heat.C(s) + H2O(g) CO(g) + H2(g), ΔH = +115 kJ/molN2(g) + O2(g) 2NO(g), ΔH = +192.5 kJ/mol

What does a catalyst do in haber process?
It speeds up the reaction that produces ammonia.
Why is a low temperature not used in the haber process?
A low temperature is not used in the Haber process because the reaction between nitrogen and hydrogen to form ammonia is an exothermic reaction, meaning it releases heat. Using a higher temperature allows for a higher reaction rate, but temperatures that are too high can lead to decreased ammonia yield due to the reverse reaction occurring.
Does temperature affect the production of ammonia from ammonia chloride?
Yes, temperature can affect the production of ammonia from ammonium chloride. Generally, higher temperatures can increase the rate of the reaction, leading to more ammonia production. However, excessively high temperatures can also cause decomposition of ammonia.
How does the concentration affect the rate and yield of ammonia?
Increasing the concentration of reactants typically increases the rate of ammonia production. However, it may not necessarily increase the yield of ammonia as the equilibrium position can be shifted depending on the reaction conditions. Increasing the concentration of reactants can favor the forward reaction, leading to higher yields of ammonia in some cases.
How does high pressure increase percentage yield of 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.
