A Cu|Cu2+ || Cu+|Cu galvanic cell is constructed in which the standard cell voltage is 0.185 V. Calculate the free energy change at 25°C when 0.561 g of Cu plates out, if all concentrations remain at their standard value of 1 M throughout the process. What is the maximum amount of work that could be done by the cell on its surroundings during this experiment?
ΔG° = J
Maximum work = J
