At high temperatures, iodine molecules can dissociate into iodine atoms. For the reaction 1₂(g) = 21 (g) Kc = 1.27 x 10-4 at 900 °C. A 65.5 g sample of l₂ is placed in a 1.00 L vessel and heated to 900 °C. What will be the molar concentration of iodine atoms, [I.], in the vessel when the system comes to equilibrium?

Question
At high temperatures, iodine molecules can dissociate into iodine
atoms. For the reaction
12(g) = 21.(g)
Kc = 1.27 x 10-4 at 900 °C. A 65.5 g sample of l2 is placed in a 1.00 L
vessel and heated to 900 °C. What will be the molar concentration of
iodine atoms, [1.], in the vessel when the system comes to
equilibrium?
