### Re: R

You use the first one (8.314 J/K*mol) because it will allow you to cancel out temperature and Faradays constant, then you would be left with J/C which equals volts.

### Re: R

I believe you use the 8.314 (Joules/ Kelvin x mol). This is just the easiest way to utilize the gas constant as the rest of the units for other variables are in similar units as R.
