Question

For each of the following reactions, indicate if the equilibrium mixture contains mostly products, mostly reactants, or both reactants and products: (10.4) a. $2 \mathrm{H}_{2} \mathrm{O}(g) \rightleftarrows 2 \mathrm{H}_{2}(g)+\mathrm{O}_{2}(g) K_{\mathrm{c}}=4 \times 10^{-48}$ b. $\mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightleftarrows 2 \mathrm{NH}_{3}(g) K_{\mathrm{c}}=0.30$ c. $2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \rightleftarrows 2 \mathrm{SO}_{3}(g) K_{\mathrm{c}}=1.2 \times 10^{9}$ d. $\mathrm{H}_{2}(g)+\mathrm{S}(s) \rightleftarrows 2 \mathrm{H}_{2} \mathrm{~S}(g) K_{\mathrm{c}}=7.8 \times 10^{5}$
