The equilibrium constants for the reaction are
N2(g)+3H2⇌2NH3(g);K1....(i)
2N2(g)+6H2⇌4NH3(g);K2.....(ii)
Equilibrium constant for (i) reaction is
K1=‌

[NH3]2

[N2][H2]3

.....(iii)
Equilibrium constant for (ii) reaction is
K2=‌

[NH3]4

[N2]2[H2]6

....(iv)
Comparing (iii) and (v)
K2=K12 or K1=√K2
