Final answer:
Ammonia can be prepared from nitrogen and hydrogen using the Haber-Bosch process. Increasing the pressure on the system can increase the yield of ammonia. This process is commonly used for industrial production of ammonia.
Step-by-step explanation:
Ammonia, the active ingredient in 'smelling salts', can be prepared from nitrogen and hydrogen. The process for making ammonia is called the Haber-Bosch process, which is the most common method used for industrial production of ammonia. It involves combining nitrogen and hydrogen under high pressure and temperature in the presence of an iron catalyst. This reaction produces ammonia as the desired product.
Increasing the pressure on the system is one way to increase the yield of ammonia. According to Le Chatelier's principle, increasing the pressure on a system at equilibrium with fewer moles of gas will shift the equilibrium towards the side with fewer moles of gas. In this case, the forward reaction producing ammonia has fewer moles of gas than the reverse reaction producing nitrogen and hydrogen, so increasing the pressure will shift the equilibrium towards the forward reaction and increase the yield of ammonia.
