(D) The balanced chemical equation for the formation of $NH_3$ is: $N_2(g) + 3H_2(g) ightleftharpoons 2NH_3(g)$.First,calculate the equilibrium constant $K_c$:$K_c = \frac{[NH_3]^2}{[N_2][H_2]^3} = \frac{(1.6 	imes 10^{-2})^2}{(1.25 	imes 10^{-2}) 	imes (4.0 	imes 10^{-2})^3}$.$K_c = \frac{2.56 	imes 10^{-4}}{(1.25 	imes 10^{-2}) 	imes (64 	imes 10^{-6})} = \frac{2.56 	imes 10^{-4}}{80 	imes 10^{-8}} = \frac{2.56 	imes 10^{-4}}{8 	imes 10^{-7}} = 0.32 	imes 10^3 = 320$.The relationship between $K_p$ and $K_c$ is $K_p = K_c(RT)^{\Delta n}$.Here,$\Delta n = 2 - (1 + 3) = 2 - 4 = -2$.Therefore,$K_p = 320(RT)^{-2}$.

The equilibrium concentrations of $N_2, H_2$ and $NH_3$ in the formation of $NH_3$ at $500 \ K$ are $1.25 \times 10^{-2} \ M, 4.0 \times 10^{-2} \ M$ and $1.6 \times 10^{-2} \ M$ respectively. The equilibrium constant $K_{p}$ at the same temperature is
