(D) The relationship between $K_p$ and $K_c$ is given by the formula: $K_p = K_c(RT)^{\Delta n}$.Here,$\Delta n = (2 + 1) - 2 = 1$.Given $K_p = 4.157 \times 10^{-4} \ bar$,$T = 1000 \ K$,and $R = 0.083 \ L \ bar \ K^{-1} \ mol^{-1}$.Substituting the values: $4.157 \times 10^{-4} = K_c(0.083 \times 1000)^1$.$K_c = \frac{4.157 \times 10^{-4}}{83} = 0.05008 \times 10^{-4} = 5.008 \times 10^{-6} \ mol \ L^{-1}$.Thus,the correct value is approximately $5.0 \times 10^{-6}$.
