Units When Using Bond Enthalpies

Postby ntruong2H » Thu Feb 09, 2017 6:32 pm

Hi, can someone please tell me what the units should be for when using bond enthalpies? Because the examples in the book vary on whether or not the units for the final measurement are reported in kJ/mol or just kJ. For example, like the problem on our quiz, what were the units supposed to be and why? Thank you.

For it's fine for your final answer to be in either kj or kj/mol. Here the mol in kj/mol is only referring to the amount of heat being absorbed or released per mole of reaction. In other words, if the reaction is being carried out with its current stoichiometric coefficients, the amount of heat being absorbed or released is
