Under standard conditions for all concentrations, the following reaction is spontaneous at 25^@C.O_2(g) + 4H^(+)(aq) + 4Br^(-) (aq) to 2H_2O (l) + 2Br_2(l) , E^@ = 0.17V If [H^+]is adjusted by adding a buffer of 0.10 M NaOCN and 0.10 M HOCN (K_a = 3.5 xx 10^(-4)), what value will E_("cell")have, and will the reaction be spontaneous at this [H^+] ?
