An electrochemical cell is constructed such that on one side

An electrochemical cell is constructed such that on one side a pure nickel electrode is in contact with a solution containing Ni2+ ions at a concentration of 3 ( 10-3 M. The other cell half consists of a pure Fe electrode that is immersed in a solution of Fe2+ ions having a concentration of 0.1 M. At what temperature will the potential between the two electrodes be +0.140 V?
