Question 18ac5

Jul 15, 2017

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, ${N}_{2} {O}_{3}$.

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)#
