Gibbs free energy for cell rxns: UNITS

Postby Sydney Wu 2M » Thu Feb 02, 2017 2:01 pm

When calculating delta G* using -nFE*, units cancel nicely to yield a result in units J. However, in previous exercises, delta G* has had units kJ.mol-1. I know you can convert J to kJ, but what are the correct units for delta G*?

I think the units are kJ/mol, but I think J/mol is also correct as long as you convert your numbers correctly.

Generally speaking delta G is reported in kJ/mol, it would be better to do the quick conversion from J to kJ.
