8.67b

In the solutions manual, it tells us that it takes 717kJ/mol to "atomize 1 mol C(gr)". What does this mean and where does the number come from? I can't find it in the tables in the book that the problem tells us to use.

The number +717 kJ/mol is given in the problem itself, and it is the standard enthalpy of sublimation of carbon. Since it is given to us directly in the problem, I don't think it is in the tables or the appendix.
