When suspected drunk drivers are tested with a Breathalyzer, the alcohol (ethanol) in the exhaled breath is oxidized to acetic acid with an acidic solution of potassium dichromate:

3CH3CH2OH(aq) + 2Cr2O7-2 (aq) + 16H+(aq)  3CH3CO2H(aq) + 4Cr+3(aq) + 11H2O (l)


If Eº for this cell is 1.30V and the standard half-cell potential of Cr2O7-2(aq) to Cr+3 is 1.358 V, what is the standard half-cell reduction potential for the conversion of acetic acid to ethanol?
◦ 2.658 V
◦ -0.058 V
◦ -2.658 V
◦ + 0.058 V
