Iodine is reacted with chlorine gas in order to form iodine monochloride with the following equation: I₂(s) +Cl₂(g) ⇌ 2ICl (g) . It is found that it occurs in a 2.0 L container, and that the reaction has now reached equilibrium. There is known to be 55 grams of solid iodine as well as a concentration of Cl₂ being 1.5*10^-4 M. The molarity of ICl is known to be 0.25 M at equilibrium as well. What is the equilibrium constant Kc for this reaction?
