12.Write out the equilibrium-constant expressions for the following. What would the value of Kc be for part (a) if the reaction had been reverseda.CO(g) + H2O(l) H2(g) + CO2(g) Kc = 1.7 x 10-1b.Fe2O3(s) + 3H2(g) 2Fe(s) + 3H2O(g) c.SbCl5(g) SbCl3(g) + Cl2(g) 13.If we start the experiment with a mixture of 0.275 mole of NOBr(g), 0.185 mole of NO(g), and 0.075mole Br2(g) in a 0.500 L container at 100oC, would more NO(g) + Br2(g) be formed or consumed? 2NOBr(g) 2NO(g) + Br2(g)Kc = 0.01414.For the reaction 2SO3(g) 2SO2(g) + O2(g), Kc is 2.71 x 10-3at 925K.
