calculate the reduction potential for hydrogen ion in a system having a perchloric acid concentration of 2.00 x 10^-4 M and a hydrogen pressure of 2.50 atm.

  • chemistry -

    2H^+ + 2e ==> H2
    E = Eo - (0.05916/2)log[H2/(H^+)^2]
    Plug and chug.

  • chemistry -

    I am given the concentration of HClO4 and a pressure for H2... how do i plug either of the givens into the equation youve shown??

  • chemistry -

    Pressure of H2 goes in in atmospheres in the numerator. (HClO4) = (H^+) and goes in in molar units in the denominator and is squared since I used 2e in the 0.05916/2 part.
