Gibbs Free energy units
Does the Gibbs free energy have to be reported in kJ per mol or can we report in J per mol?

Gibbs free energy is typically reported in kJ per mol because the values for Gibbs free energy are typically large enough to be reported in kJ per mol. Mathematically speaking, there is no difference between reporting Gibbs free energy in kJ/mol vs J/mol as long as you make it clear that you are using the J/mol units.

I believe that in class, we have been mostly using Gibbs free energy in kJ/mol but as Esha said, you can technically put it into whatever units you want it to be in.

Re: Gibbs Free energy units
I'm pretty sure the units can be either or, but you just have to make sure your units are consistent throughout your entire calculation or then you'll have answers of different degrees.

Re: Gibbs Free energy units
Both units can be used, however if the numbers are very large kJ are typically more convenient to use. However, when doing calculations, make sure that all units cancel which often depends on the units of the constants that you are given. I hope this helps!
