- 1.02 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 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.
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.
By using the information in the ALEKS
