Units for Gibbs
When solving for G using H and S, if the H is given in J/mol, should we covert the value to KJ so that our final answer is in the SI unit is in KJ or just be consistent with the units?

Re: Units for Gibbs
I dont think it matters, as long as it makes sense. For example, using joules would be better if you get something like 57 J, because that would be 0.057 kJ and it just looks neater with J. On the same note, if you get 57000 J, it might be better to convert that to 57 kJ
Re: Units for Gibbs
It doesn't matter which one you convert to, as long as you make sure both are in the same units

Re: Units for Gibbs
Doesn't matter as long as it is easy to read (ie Don't have it in joules if you just have it look neater in kj like 10 kJ instead of 10000J) cause the point of science is to be universal and for our data to be easily read and interpreted

Re: Units for Gibbs
I don't think it matters whether the final answer is in J or kJ, but make sure when you're plugging them in the equation they're in the same units.

Re: Units for Gibbs
It shouldn't matter. However almost all of the answers in the textbook are given in kJ.

Re: Units for Gibbs
As long as they are the same units it doesn't matter, whatever is easier for you.

Re: Units for Gibbs
Either J or kJ should be fine for the final answer, as long as you're consistent with units while you're doing the calculation so that the number ends up being correct.
