Question 1
A particular 12V battery is based on a reaction having a standard cell potential,
E° = +1.92 V. What happens when the battery "dies"?
◦
E° = 0 V and
E = 12 V
◦
E° = 12 V and
E = 0 V
◦
E° = +1.92 V and
E = 12 V
◦
E° = +1.92 V and
E = 0 V
Question 2

◦ an alkaline dry cell
◦ a nickel-metal hydride battery
◦ a lithium battery
◦ an alkaline cell
