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.

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.

You use the 8.314 value because it allows you to cancel out the units properly.
