Ammonia is created using the Haber-Bosch process:
A reaction vessel is used to combine the nitrogen and hydrogen gas until the vessel is at equilibrium.
What will happen to the system if ammonia is removed from the vessel?

What will happen to the system if ammonia is removed from the vessel?
When a system is at equilibrium, it is possible to predict how a system will respond to sudden changes using Le Chatelier's principle. In this scenario, ammonia has been removed from the system. This will cause the reaction to produce more ammonia, and proceed to the right in order to reestablish equilibrium.

What would you predict to happen if the pressure of the vessel increases?

According to Le Chatelier's principle, a change in pressure will cause a shift in order to counteract the pressure change. When the pressure of a vessel is increased, the side of the reaction with fewer gas molecules will be preferred in order to minimize contact between gas molecules. For this reaction, there are four gas molecules on the left side and two gas molecules on the right side. As a result, the products side will be preferred and more ammonia will be created.

Based on the given information, under what conditions should this reaction be carried out to promote the most formation of product?
Based on the given information, under what conditions should this reaction be carried out to promote the most formation of product?
High pressure will favor the side of the reaction with fewer moles of gas, which in this case is the product side.
The reaction is exothermic, meaning that it generates heat. By removing heat from the reaction, we are constantly stressing the system towards the product side.
Finally, the reaction should occur under a lamp. This is due to the hv symbol above the double arrows, which signifies that light promotes the reaction. Note: had the hv symbol been below the double arrows, the reaction should have occurred in the dark.
