A certain half-reaction has a standard reduction potential +0.10 V. An engineer

Question

A certain half-reaction has a standard reduction potential +0.10 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? O 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. O no minimum Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? O yes, there is a maximum. red if so, check the "yes" box and calculat the maximum. Round your answer to 2 O no maximum decimal places. If there is no upper limit, check the "no" box. 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

Ecell = Ecathode - Eanode

Eanode = 0.1

For cell to be functional Ecell > 0

For Cathode there is a minimum reduction potential exists which will satisfy above eqn i.e

Ecell = Ecathode - Eanode > 0

Ecathode - Eanode > 0

Ecathode > Eanode

Ecathode > 0.1 V

Also there is a limit to Ecathode values

From electrode potential graph

highest Ecathode value is for Flourine = 2.87 V

Possible cathode for anod ecan be

Cu 2+ + 2e- -> Cu Ecathode = 0.34 V
