Gaseous hydrogen iodide is placed in a closed container at 425°C, where it partially decomposes to hydrogen and iodine: 2HI (g) = H2 (g) + l2 (g). At equilibrium, it is found that [HI] - 3.53 x 10 M, [H¿] = 4.79 × 10 M and [1] =4.79 x 10 M. What is the value of Keq at this temperature?

Question
1. Gaseous hydrogen iodide is placed in a closed container at 425°C, where it partially
decomposes to hydrogen and iodine: 2HI (g) = H2 (g) + l2 (g). At equilibrium, it is found that [HI]
= 3.53 x 10* M, [H2] = 4.79 × 10M and [12] =4.79 × 10* M. What is the value of Keq at this
temperature?
