Ammonia is produced industrially by the Haber process using nitrogen and hydrogen.
The balanced equation for this reaction is: N2(g)+3H2(g)⇌2NH3(g)\text{N}_2\text{(g)} + 3\text{H}_2\text{(g)} \rightleftharpoons 2\text{NH}_3\text{(g)}N2(g)+3H2(g)⇌2NH3(g)
The graph below shows the percentage yield of ammonia at a constant pressure of 200 atm200\text{ atm}200 atm across a range of temperatures:
Answer the following questions:
State the physical state of ammonia when it is cooled and separated from the unreacted gases in the condenser during the industrial process.
Explain how the balanced equation shows that the atom economy for the production of ammonia is 100%100\%100%.
Describe the relationship between temperature and the percentage yield of ammonia shown in the graph.
