At 600°C, gaseous CO and Cl2 are mixed together in a closed container. At the instant they are mixed, their concentrations are CO = 0.79 mol/L and Cl2 = 0.69 mol/L. After equilibrium is established, their concentrations are CO = 0.25 mol/L and Cl2 = 0.15 mol/L. Evaluate the equilibrium constant for the reaction
