A certain half-reaction has a standard reduction potential Ered-0 V. An engineer

Question

A certain half-reaction has a standard reduction potential Ered-0 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.20 V of electrical power. The cell will operate under standard conditions Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? yes, there is a minimum red If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box no minimum Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? yes, there is a maximum If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box no maximum By using the information in the ALEKS Data tab, write a balanced equation describing a half reaction that could be used at the cathode of this cell Note: write the half reaction as it would actually occur at the cathode

Explanation / Answer

yes, there is a minimum. E0red = +1.20 v

because, E0cell = E0cathode - E0anode

                 = 1.2 - 0

                 = 1.2 V

SO that, E0cthode must be = 1.2 V

no maximum.

cathode, that could be used.

half-reaction : ClO4 + 2 H+ + 2 e ---> ClO3 + H2O E0 = +1.20 v
