Cell potential and Standard Cell potential.?

Cell potential and standard cell potential? Please help?

I'm so confused... I'm supposed to calculate the standard cell potential and the cell potential of

Pt (inert), H2 (5.42 atm) I H+ (.00476 M) I O2 (3.60 atm), Pt (inert)

I'm not asking for an answer, but could someone please show me how to set this up?

Update:

Well yes, but how does pressure factor into the equation?

    The standard cell is at 25o C and 1 molar

    If you differ from standard conditions, you should calculate the standard cell and then adjust with the Nernst eq.

    confident. only run the reaction backward. as an occasion, Cu ===> Cu2+ + e- E = -0.34V Cu2+ + 2e- ===> Cu E = +0.34V in case you're utilising a cellular to produce electricity (galvanic or voltaic cellular), then the sums of the two cellular potentials might desire to be (+). in case you're utilising electricity to produce a chemical substitute like nickel plating (electrolytic cellular), then the sum would be (-), and you supply the version from exterior.
