2. The overall reaction between carbon monoxide and chlorine in the gas phase to produce phosgene is: CO+Cl2COCl2 Two different mechanisms have been proposed to explain this reaction: Mechanism I. Cl22lfastreactioninequilibrium,Cl+COCOClfastreactioninequilibrium,COCl+Cl2k3COCl2+ClCl+COCl2k4COCl+Cl2 Mechanism II. Cl22Clfastreactioninequilibrium,Cl+Cl2Cl3Cl3+COK6COCl2+ClCl+COCl2k7CO+Cl3 a. Are the mechanisms consistent with the overall reaction? b. Derive the expressions for the rate of phosgene formation for both mechanisms. c. Indicate whether kinetic measurements can determine which mechanism is correct (assuming that the values of the rate constants for the reactions are not known)
