ICE Problem: Calculate Final Concentrations
Phosgene, COCl2 (g), is an extremely toxic gas. It was used during World War I. Today it is used to manufacture pesticides, pharmaceuticals, dyes, and polymers. It is prepared by mixing carbon monoxide and chlorine gas.
CO (g) + Cl2 (g) = COCl2 (g) <-- the equal sign should be the sign for foward and reversible reactions ( arrows facing both ways )
0.055 mol of CO (g) and 0.072 mol of Cl2 (g) are placed in a 5.0 L container. At a certain temperature, the equilibrium constant is 20. What are the equilibrium concentrations of the mixture?
Advantages and disadvantages of using Alternative Fuel and Would you consider buying one of these in the future? Why or Why Not and Why do you think there are not more of these vehicles in use?
