Question

A certain half-reaction has a standard reduction potential +0.14 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 0.80 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 hall reaction used at the cathode of this cell can have? ves, there is a minimum. - Oy If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower imit, check the "no" box no minimum x 5 ? Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? ves, there is a maximum. Ed - v If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper imit, check the "nobox. 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.
