Units for enthalpy

Postby Katelyn 2E » Mon Feb 12, 2018 3:21 pm

Can someone refresh my memory as to what Dr. Lavelle said in class today regarding units for enthalpy? My impression is that he said kJ and kJ/mol could be accepted interchangeably (when we were doing the Hess's Law question).

I think he said we don't have to be too specific about the difference between kJ/mol and kJ. For the test and examples we cover in class we usually just use kJ.

It's safe to just look at what you are given in the question (if enthalpy is in kj/mol in the question then your answer should be in kj/mol, etc.) but you can also assume that you can put just kj for your answer if the question implies that you're only talking about one mole of a substance.
