question 40

Multiple Choice

What is the correct equilibrium constant expression for the following reaction? C₄H₁₀(g) + $\frac{13}{2}$ O₂(g) ⇌ 4CO₂(g) + 5H₂O(g)

• A) \(K=\frac{P_{\mathrm{CO}_{2}} \times P_{\mathrm{H}_{2} \mathrm{O}}}{P_{\mathrm{C}_{4} \mathrm{H}_{10}} \times P_{\mathrm{O}_{2}}}\)
• B) \(K=\frac{\left(P_{\mathrm{CO}_{2}}\right)^{4} \times\left(P_{\mathrm{H}_{2} \mathrm{O}}\right)^{5}}{P_{\mathrm{C}_{4} \mathrm{H}_{10}} \times\left(P_{\mathrm{O}_{2}}\right)^{13 / 2}}\)
• C) \(K=\frac{\left(P_{\mathrm{CO}_{2}}\right)^{8} \times\left(P_{\mathrm{H}_{2} \mathrm{O}}\right)^{10}}{\left(P_{\mathrm{C}_{4} \mathrm{H}_{10}}\right)^{2} \times\left(P_{\mathrm{O}_{2}}\right)^{13}}\)
• D) \(K=\frac{\left(4 P_{\mathrm{CO}_{2}}\right)^{4} \times\left(5 P_{\mathrm{H}_{2} \mathrm{O}}\right)^{5}}{P_{\mathrm{C}_{4} \mathrm{H}_{10}} \times\left(\frac{13}{2} P_{\mathrm{O}_{2}}\right)^{13 / 2}}\)
• E) \(K=\frac{P_{\mathrm{C}_{4} \mathrm{H}_{10}} \times\left(P_{\mathrm{O}_{2}}\right)^{13 / 2}}{\left(P_{\mathrm{CO}_{2}}\right)^{4} \times\left(P_{\mathrm{H}_{2} \mathrm{O}}\right)^{5}}\)
