Question

A CrCrN Ni galvanic cell is constructed in which the standard cell voltage is 0.490 V. Calculate the free energy change at 25°C when 0.907 g of Ni 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? Maximum work Submit Answer 3 question attempts remaining
