An Electrоchemicаl cell is cоnstructed with а zinc metаl anоde in contact with a 5.2 x 10-2 M solution of zinc (II) nitrate and a silver cathode in contact with a 4.20 x 10-3 M solution of silver(I) nitrate. What is the voltage measured across the cell at the moment the reaction begins? The reaction is run at 298 K.
