kJ or kJ/mol?

Postby Mackenzie Sober 2E » Sun Feb 12, 2017 1:22 pm

Yesterday in one of the review sessions the TA said something about how delta G should always be reported as kJ per mole of reaction. I thought we were only supposed to include per mole if the question specifically states per mole. Can someone please clarify?

We are always supposed to include the units KJ/mol regarding delta G. The book made mistakes and only included KJ in some of their answers to the practice problems about Gibbs, but they are supposed to be KJ/mol.

we measure both enthalpy and Gibbs free energy in kJ mol-1 (kilojoules per mole).
