A certain half-reaction has a standard reduction potential E -0.43 V. An engineer proposes using this haif-reaction at the cathode of a galanic oell that must provide at least 1.40 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 that the anode of this cell can heve half-reaction used et O yes, there in a minimum T, check box and calte mum. Round your answer decimal places there mit, check the "ne imum Is there potential that the haif reation used at the anode of this ce can have maimum tandard reducton ye there amaum f check "yes" o and ate Round your places ther imun Imt, check the b By using the information the ALES Data ta, wite a l describng a haf reaction that could be used at the ande Tthis call Notewrite the haif reactien actually ocu anode
