using the Nernst equation

Postby emmaferry2D » Fri Mar 12, 2021 9:49 pm

When using the Nernst equation and a given pressure of a gas is in bar or Torr do you need to convert it to atm? or are you able to use the different values of R that match that pressure value

Hi, I think that using bar is okay but if it's Torr, you should convert it into atm.

I think you can only use bar or atm for pressure, because in this class, we consider them approximately the same. For any other units, we would need to convert.

I would convert Torr to Atm but with Barr I think you're fine

In class I think Dr. Lavelle said that for 14A and B we approximate bar=atm and those two are probably the most common units we will see in the problems.
