ОВР очень сложная реакция!!!

[gena]

Cr2(SO4)3+K2S2O8+HNO3=
Ph=3 Написать уравнение реакции, расставить коэффициенты методом ённо-электронного баланса и рассчитать ЭДС реакции, и Константу дис.
З.ы. Кто сделает, тот просто гений личноя теряюсь в догадках что там может получится (Cr207 нет, т.к. нет OH, NO тоже не уверен)!!!
