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 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) ⟶ COCl2 (g) (fast, k3 the rate constant)(a) Write the overall reaction.

Problem

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, krepresents 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) ⟶ COCl2 (g) (fast, k3 the rate constant)

(a) Write the overall reaction.
