Calculate the electrode potential at 25^...

Calculate the electrode potential at `25^@C` of `Cr_2O_7^(2–)//Cr^(3+)` electrode at pOH = 11 in a solution of 0.01 M both in `Cr^(3+)` and `(Cr_2O_7^(2–))` = 1.33 V. If this electrode is coupled with a hydrogen gaseous electrode at pH = 6, find the emf of the spontaneous cell.
