Multiple Choice

What is the correct equilibrium constant expression for the formation of ammonia gas from nitrogen gas and hydrogen gas?

• A) \(K=\frac{P_{\mathrm{NH}_{3}}}{P_{\mathrm{N}_{2}} \times P_{\mathrm{H}_{2}}}\)
• B) \(K=\frac{\left(2 P_{\mathrm{NH}_{3}}\right)^{2}}{P_{\mathrm{N}_{2}} \times\left(3 P_{\mathrm{H}_{2}}\right)^{3}}\)
• C) \(K=\frac{P_{\mathrm{N}_{2}} \times\left(3 P_{\mathrm{H}_{2}}\right)}{\left(2 P_{\mathrm{NH}_{3}}\right)}\)
• D) \(K=\frac{\left(P_{\mathrm{NH}_{3}}\right)^{2}}{P_{\mathrm{N}_{2}} \times\left(P_{\mathrm{H}_{2}}\right)^{3}}\)
• E) \(K=\frac{P_{\mathrm{N}_{2}} \times\left(P_{\mathrm{H}_{2}}\right)^{3}}{\left(P_{\mathrm{NH}_{3}}\right)^{2}}\)
