For the ammonia synthesis reaction,
the equilibrium conversion to ammonia is large at 300 K, but decreases rapidly with increasing T. However, reaction rates become appreciable only at higher temperatures. For a feed mixture of hydrogen and nitrogen in the stoichiometric proportions,
(a) What is the equilibrium mole fraction of ammonia at 1 bar and 300 K?
(b) At what temperature does the equilibrium mole fraction of ammonia equal 0.50 for a pressure of 1 bar?
(c) At what temperature does the equilibrium mole fraction of ammonia equal 0.50 for a pressure of 100 bar, assuming the equilibrium mixture is an ideal gas?
(d) At what temperature does the equilibrium mole fraction of ammonia equal 0.50 for a pressure of 100 bar, assuming the equilibrium mixture is an ideal solution of gases?
