A certain half-reaction has a standard reduction potential E°red = -0.22 V. An engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least 0.70 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 cathode of the cell.
Is there a minimum standard reduction potential hat the half-reaction used at the anode 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.
