Ammonia is produced by the Haber process, in which nitrogen and hydrogen are reacted directly using an iron mesh impregnated with metal oxides as a catalyst. For the reaction N2(g) + 3H2(g) â 2NH3(g) equilibrium constants as a function of temperature are 300ËC, 4.34 x 10^-3 atm-2 500ËC, 1.45 x 10^-5 atm-2 600ËC, 2.25 x 10^-6 atm-2

a. Is the reaction exothermic or endothermic? b. Typical conditions used for producing ammonia are temperatures of 400 to 500ËC and total pressures of 200 to 600 atm. Why are these conditions chosen?
