At 298 K the following equilibria are established: (1) CO(g)+12 O2(g)⇌CO2(g)K1=1.5×1010\mathrm{CO}(g) + \tfrac12\,\mathrm{O_2}(g) \rightleftharpoons \mathrm{CO_2}(g) \qquad K_1 = 1.5\times10^{10} (2) H2O(g)⇌H2(g)+12 O2(g)K2=3.5×10−9\mathrm{H_2O}(g) \rightleftharpoons \mathrm{H_2}(g) + \tfrac12\,\mathrm{O_2}(g) \qquad K_2 = 3.5\times10^{-9} Determine the equilibrium constant, KK, for the water-gas shift reaction CO(g)+H2O(g)⇌CO2(g)+H2(g)\mathrm{CO}(g) + \mathrm{H_2O}(g) \rightleftharpoons \mathrm{CO_2}(g) + \mathrm{H_2}(g) at 298 K. a) 4.3×10184.3\times10^{18} b) 7.27.2 c) 5.3×1015.3\times10^{1} d) 4.34.3
