Calculate equilibrium concentrations A closed system initially containin 1.000 x 10-3 M H2(g) and 2.000 x 10-3 M 12(9) at 448 °C is allowed to form HI and reach equilibrium. Analysis of the equilibrium mixture shows that the concentration of HI is 1.87 x Calculate K, at 448 °C for the reaction. a) 935 b) 27000 c) 4.00 d) 50.5
