Here we're looking to relate the standard enthalpy of formation of the reactants to the products in order to find the reactions, and in this case, #N_2O_3#.

#DeltaH_(rxn)^° = SigmaDeltaH_(p)^° - SigmaDeltaH_(r)^°#

In most chemistry classes, you will be given these data, except in maybe advanced courses. I found these in the table in back of my text.

#DeltaH_(rxn)^° = [2*90.37+0] - 86.6#
#DeltaH_(rxn)^° approx (94.1kJ)/(mol)#
