A certain half-reaction has a standard reduction potential Ered = +0.55 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 0.90 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? 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. 0 yes, there is a minimum. Ered = V no minimum Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? 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. Oyes, there is a maximum. E-v red 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. ローロ a х G

Transcribed Image Text:A certain half-reaction has a standard reduction potential Ered = +0.55 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that
must provide at least 0.90 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?
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.
0
yes, there is a minimum.
Ered = V
no minimum
Is there a maximum standard reduction
potential that the half-reaction used at
the cathode of this cell can have?
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.
Oyes, there is a maximum.
E-v
red
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.
