Calculate the standard Gibbs free energy change for the reaction that occurs when a cell consisting of a nickel electrode and a silver electrode is connected, given that the nickel electrode is immersed in a solution containing 0.010 M Ni2+ ions and the silver electrode is immersed in a solution containing 0.20 M Ag+ ions. The standard reduction potential for the Ni2+/Ni half-cell is -0.25 V and for the Ag+/Ag half-cell is +0.80 V.
