Question

Use heat of formation data from Appendix E to calculate the change in the standard heat of reaction for

Answer 1

We don't have access to appendix E, but I'll describe how to do the problem using the data in that appendix.

Look up the standard heat of formation for ClO(g). That will be the total heat of formation for the products, since the heat of formation of O2 is zero. Next, look up the heat of formation for ClO2(g) and for O(g), and add them together. That will be the heat of formation for the reactants. Then do ∆Hproducts - ∆Hreactants and that will give you the heat of reaction.
