Q1

What is the osmotic pressure exerted by a solution of 2M CaCl2 at room temperature? (R=0.082 L*atm/K/mol)

COCl2 (g) ⇌ CO (g) + Cl2 (g)

Initially a reaction chamber contains only 2 moles of COCl2, after the reaction has reached the equilibrium shown above the pressure is measures to be 2.60 atm. What is the most likely cause for the increase in pressure?
