Units for delta G calculations w/E

Postby Payton Kammerer 2B » Sun Feb 23, 2020 6:10 pm

The units listed in the solutions manual for the delta G under standard conditions is kj/mol, and I am confused as to where the /mol comes from.
The equation is G=-nFE, and n is the number of moles, so shouldn't that cancel with the /mol in the unit of Faraday's constant?

A lot of times we separately divide the final answer by moles in order to get those units. It's similar to how in the thermo unit, when we calculated delta H of formation we divided by mol to get J/mol even though you normally get just joules by doing products-reactants.
