A reaction is prepared by adding 2.000 mol each of H2, 12, and HI gases to a 1.0 L container. They are allowed to come to equilibrium, following the reaction: H2 (g) + I2(9) = 2HI(g) At the steady-state, 0.743 mol of HI remained in the container. What is the equilibrium constant Kc for this reaction under these conditions?
