Iodine gas and bromine gas combine to form iodine monobromide according to the following equation with an equilibrium constant of 1.2 x 102 at 150 0C. I2 (g) + Br2 (g) <==> 2IBr (g)An empty 5.00 L flask is filled with 0.0245 moles of hydrogen gas and 0.0245 moles of iodine gas at 150 0C. Calculate the concentration of iodine monobromide gas when equilibrium is reached.
