Today, ammonia is synthesized through a series of reactions (called the Haber-Bosch process) that take place between methane, air (which is four parts N2, one part O2), and potassium carbonate: 7 CH4(g) + 8 N2(g) +2 O2(g) + 17 H2O(g) + 7 K2CO3(s) ⇀↽ 16 NH3(g) + 14 KHCO3(s) What is the equilibrium expression for the Harber-Bosch process? 1.
