What is the value of Kc at this temperature?

Question

Gaseous hydrogen iodide is placed in a closed container at 425 C, where it partially decomposes to hydrogen and iodine: 2HI(g) <==> H2 (g) I2 (g). At equilibrium it is found that [HI] = 3.56×10−3 M, [H2] = 4.83×10−4 M, and [I2] = 4.83×10−4 M.

Answer 1

[Answer:

Kc = [products] / [reactants]

Kc = {[I2][H2]} / [HI]²

Kc = [(4.83×10^−4)(4.83×10^−4)] / (3.56×10^−3)² = answer ]
