The Phosgene COCl2 is chemical warfare gas commonly called mustard gas. It decomposes as written below. At 900 C, the Kc = .83. Presume 400 mol of COCl2 are admitted into a2.00 L container at 900 C. Explain what will the equilibrium concentrations of CO, CL2 and COCl2? Use the quadratic for this one.
COCl2 <=======> CO + Cl2
