A sealed 1.0 L flask contains the reaction H2(g)+I2(g)⇌2HI(g)\text{H}_2(g)+\text{I}_2(g)\rightleftharpoons 2\text{HI}(g). The system is at equilibrium at a certain temperature. The equilibrium concentrations are: [H2]=0.20 M[\text{H}_2]=0.20\,M, [I2]=0.20 M[\text{I}_2]=0.20\,M, and [HI]=0.80 M[\text{HI}]=0.80\,M. What is the value of KcK_c for the reaction at this temperature?
