Dear Netters:

Consider the reaction

Cl2O4 + 2 O3 ----> Cl2O6 + 2 O2

The absolute energy values at MP2 level for 

Cl2O4 = - 1218.929344        O3 = -224.869545
Cl2O6 = -1368.803238         O2 = -149.899877

at MP2 level the energies of the products (cl2o6 + 2o2) is

   -1368.803238 - 149.899877 - 149.899877  =  - 1668.602992

and the energies of the reactants ( cl2o4 + 2O3) is

   -1218.929344 - 224.869545 - 224.869545 = - 1668.668434

My question is, with the energy difference values can we say that
~~~~~~~~~~~
the reaction is endothermic and the reaction is not a favourable one.

Please note that experimental work has reported that a virtually
quantitative conversion of Cl2O4 to Cl2O6 has been observed by the
same reaction.

Every comments will be valuable.
Thanks in advance
