Chapter 13, Problem 62APP

For each of the following reactions, indicate if the equilibrium mixture contains mostly products, mostly reactants, or both reactants and products: $(13.4)$
a. $2{\text{H}}_2\text{O}(g)\rightleftarrows 2{\text{H}}_2(g)+{\text{O}}_2(g)K_{\text{c}}=4\times {10}^{-48}$
b. ${\text{N}}_2(\text{g})+3{\text{H}}_2(g)\rightleftarrows 2{\text{NH}}_3(g)K_{\text{c}}=0.30$
c. $2{\text{SO}}_2(g)+{\text{O}}_2(g)\rightleftarrows 2{\text{SO}}_3(g)K_{\text{c}}=1.2\times {10}^9$
d. ${\text{H}}_2(g)+\text{S}(s)\rightleftarrows 2{\text{H}}_2\text{S}(g)K_c=7.8\times {10}^5$
