Solution: The reaction of CO with Cl2 gives phosgene (COCl2), a nerve gas that was used in World War I. Use the mechanism shown here to complete the following exercises:Cl2 (g) ⇌ 2 Cl (g) (fast, k1 represents t

The reaction of CO with Cl₂ gives phosgene (COCl₂), a nerve gas that was used in World War I. Use the mechanism shown here to complete the following exercises:

Cl_{2 (g)} ⇌ 2 Cl _(g) (fast, k₁ represents the forward rate constant, k₋₁ the reverse rate constant)
CO_(g) + Cl_(g) ⟶ COCl_(g) (slow, k₂ the rate constant)
COCl_(g) + Cl_(g) ⟶ COCl_{2 (g)} (fast, k₃ the rate constant)

(a) Write the overall reaction.
