A certain half-reaction has a standard reduction potential e ed =-0.80 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 0.60 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...
