30 pts stored In sampie Problem8 lodine (L,) and bromine (Br,) are added to a solution containing iodide ) d hromide (Br) 10ns. What reaction would occur if the concentration of each species is1M? The electrode otentials for the reactions are: I,/-0-54 V,Br,/Br Po Solution. The reaction can be either Br,/Br-=1-08 v Br+2 I 2Brr+I, or I,+2Br 21+Bt For 1st reaction, E.M.F. = E° Br /Br I=108 -0-54 = 054 V For 2nd reaction, E.M.F. = E°, E° =0-54-1-08=-054 Br, As E.M.E. is positive for the 1st reaction, hence the cell reaction is Br,+2I 2 Br +I
