At a high temp. Equal concentrations of 0.200 mol/L of H_2 (g) and I_2 (g) are initially present in a flask. The H_2 and I_2 react according to the balanced equation

H_2 (g) + I_2(g) ----- 2 HI(g)

Explain when equilibrium is reached, the concentration of H_2 has decreased to 0.046 mol/L. what is the equilibrium constant, Kc, for the reaction?
