The equation of the reaction is : $$\ce{N_2(g) + 3 H_2(g) <=> 2 NH_3(g)} $$

The equilibrium constant for this reaction have been summarized in the Chemistry Data BookChemistry Data Book, by J. G. Stark and H.G. Wallace, Jon Murray, London, 20062006. At $400°$C,$\pu{400 °C},$ $K_p$ is $40.7$ $atm^{-2}$$\pu{40.7 atm^{-2}}.$ At $500°$C,$\pu{500 °C},$ $K_p$ is equal to $0.035$. So, at $250°$C,$\pu{250 °C},$ $ NH_3$$\ce{NH3}$ is not significantly decomposed.
