Ammonia is produced by the Haber process, in which nitrogen and hydrogen are reacted directly using an iron mesh impregnated with oxides as a catalyst. For the reaction

N2(g) + 3H2(g) <=> 2NH3(g)

equilibrium constants (Kp values) as a function of temperature are

300 degrees C, 4.34x10^-3

500 degrees C, 1.45x10^-5

600 degrees C, 2.25x10^-6

Is the reaction exothermic or endothermic?
