How would we use the values we are given to calculate S.H.E?

[Jayasree Peri 2J]

So, the equation that we're using is: E = Eº - (RT/nF)lnQ.
In this case, because this is S.H.E., our Eº is going to be 0, meaning that our E will be -(RT/nF)lnQ. n is the number of electrons transferred; to find this, write out your half-reactions and balance them. F is the Faraday constant, which is 96485 J/(V • mol e^-). To find Q, you can actually just use the pressure and the concentration together. After determining your reactants and products, just plug in the given values (whether it's pressure or concentration) into your Q; there's no need to convert using PV=nRT because this is a Galvanic cell.

Appreciate it. Thanks a lot!
