What would the potential of a standard hydrogen (S.H.E.) electrode be if it was under the following conditions?
[H+] = 0.38
P(H2) = 3.8
T = 298 K

  • Chemistry - ,

    I assume that's 3.8 atm.
    2H^+ + 2e ==> H2
    E = Eo - (0.0592/2)log[(pH2/(H^+)^2]

  • Chemistry - ,

    Wait but there is no Eo

  • Chemistry - ,

    Yeah then how would you calculate it

  • Chemistry - ,

    I had a similar question why doesn't Eo count is it because it is under standard conditions?

  • Chemistry - ,

    Eo is zero, right? :-)
    The SHE under standard condition is always 0.
