Write the equilibrium-constant expression for the reaction shown in terms of [A], [B], [C], and [D]: A(g) + B(g) ⇌ 2 C(g) + D(g) Note that Kc, which is sometimes symbolized as K or Keq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, Kc means the same thing as K and Keq. Kc = [C]^2[D] / [A][B]
For the following three reactions $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$, equilibrium constants are given: [2008] (a) $\mathrm{CO}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightleftharpoons \mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2}(\mathrm{~g}) ; \mathrm{K}_{1}$(b) $\mathrm{CH}_{4}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightleftharpoons \mathrm{CO}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{~g}) ; \mathrm{K}_{2}$ (c) $\mathrm{CH}_{4}(\mathrm{~g})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) \rightleftharpoons \mathrm{CO}_{2}(\mathrm{~g})+4 \mathrm{H}_{2}(\mathrm{~g}) ; \mathrm{K}_{3}$ Which of the following relation is correct? (a) $\mathrm{K}_{1} \sqrt{\mathrm{K}}_{2}=\mathrm{K}_{2}$ (b) $\mathrm{K}_{2} \mathrm{~K}_{3}=\mathrm{K}_{1}$ (c) $\mathrm{K}_{3}=\mathrm{K}_{1} \mathrm{~K}_{2}$ (d) $\mathrm{K}_{3} \cdot \mathrm{K}_{2}^{3}=\mathrm{K}_{1}^{2}$
