Problem 8.63c typo?

Postby Sydney Wu 2M » Fri Jan 13, 2017 7:02 am

Appendix 2A tells that delta hf* for K2S(aq) is -471.5. The answer in the textbook and SSM uses -417.5. Which is the correct delta hf* value?

I would stick with the appendix value for the problem. On future quizzes and exams, there will be a table of enthalpy values for you to reference.

I was confused by this problem as well, however this link should clear up any confusion: ... rs_6Ed.pdf

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
