A student ran the following reaction in the laboratory at 546 K: COCl2 (g) CO (g) + Cl2 (g)

When she introduced 0.723 moles of COCl2 (g) into a 1.00 liter container, she found the equilibrium concentration of Cl2 (g) to be 3.38×10-2 M.

Calculate the equilibrium constant, Kc, she obtained for this reaction.

Kc =
