The equilibrium constant for the formation of HI from molecular iodine in the gas phase H2(g)+I2(g)<->2HI(g).

The equilibrium constant for the formation of HI from molecular iodine in the gas phase H2(g) + I2(g)<->2HI(g) is 54.3 at 4.30 centigrades. Suppose that in a certain experiment, we place 0.243 mole of H2, 0.146 mole of I2 and 1.98 mole of HI all in a 1.00 L container at 430 centigrades. Is the final and initial concentration have the same value for Kc?
