Pt/I2,I-1 //Au+3/Au

according to the given galvanic cell representation

left side electrode acts as anode and right side electrode acts as cathode.

oxidation half reaction at anodeÂ Â Â Â Â Â Â Â Â Â Â Â [ 2 I^1- -------------------- I2 + 2e-]x3

reduction half reaction at cathodeÂ Â Â Â Â Â [ Au+3 +3 e- ----------------- Au]x2

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -----------------------------------------------------------------

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 6 I^{1-Â Â +} 2 Au⁺³Â Â ------------------- 3 I2 + 2 Au

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ----------------------------------------------------------------------------

E0 of I2/I^1- = 0.535V Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â E0 of Au+3/Au = 1.50V

E0 cell = E0 cathode - E0 anode

E0cell = 1.50 - 0.535

E0cell = 0.965V

Totally 6 electrons are transferred .
