Q:The following Rice-Herzfeld mechanism has been suggested for the formation of phosgene COCl2: (1)cl2=2cl                                [K1=A1×e^_Ea1/RT]
(2)2cl=cl2                                [K2=A2×e^_Ea2/RT]
(3)cl+co=cocl.                        [K3=A3×e^_Ea3/RT]
(4)cocl=cl+co.                        [K4=A4×e^_Ea4/RT]
(5)cocl+cl2=cocl2+cl          [K5=A5×e^_Ea5/RT]
A) Assuming steady-state approximation for [Cl] and [COCl], what is the rate law for the formation of COCl2?

B) Assume that the reactions (1) to (4) are much faster than reaction (5). What is the rate law for the formation of COCl2?

C) What is overall pre-exponential factor of reaction, if steps (1) to (4) are much faster than (5)?

D) What is overall activation energy of reaction, if steps (1) to (4) are much faster than (5)?
