C.
The rate law for the formation of phosgene, COCl2, from chlorine, Cl2, and carbon monoxide, CO, is unknown. Suggest a mechanism for this reaction that is consistent with this rate law and draw the reaction pathway. Hint: Cl formed from the dissociation of Cl2 is one of the two active intermediates.
d. Suggest an active intermediate(s) and mechanism for the reaction H2 + Br2 -> 2HBr. Use the PSSH to show whether or not your mechanism is consistent with the rate law.
