Consider this cell running under standard conditions:
Ni(s) |Ni2 + (aq)||Cu + (aq) | Cu(s)
a. Is this cell a voltaic or an electrolytic cell? How do you know?
b. Does current flow in this cell spontaneously?
c. What is the maximum cell potential for this cell?
d. Say the cell is connected to a voltmeter. Describe what you might see for an initial voltage and what voltage changes, if any, you would observe as time went by.
e. What is the free energy of this cell when it is first constructed?
e. Does the free energy of the cell change over time as the cell runs? If so, how does it change?
