Use the equilibrium constants for reactions (a) and (b) at 1000 K to calculate the equilibrium constant for reaction (c), the water-gas shift reaction, at that temperature. (a) CO(g) + 1⁄2 O2(g) uv CO2(g) Kc = 1.1 * 1018
(b) H2O(g) uv H2(g) + 1⁄2 O2(g) Kc = 7.1 * 10-12
(c) CO(g) + H2O(g) uv CO2(g) + H2(g) Kc=?
