Problem 8.71

[Gurkriti Ahluwalia 1K]

in the solutions manual, to solve this table, the value given for electron affinity is subtracted instead of added like all the other values (with the exception of the energy used to form the compound). Is this because affinity for electrons requires energy from the compound to take in electrons? or am i missing something?

We didn't cover the concepts of this question in class so you don't need to know how to do it. 71 isn't listed as one of the homework problems to choose from on the syllabus. If you want to figure it out for your own sake no one's stopping you, just read the section that covers it in the book!
