![20. Due to COVID-19 coupled with erratic power supply from ZESCO, you decide to play
around with galvanic cells and you construct a zinc-copper battery operating at a zero
resistant small light emitting diode (L.E.D) at 25°C as follows:
Zn | Zn²*(0.10 M) || Cu2* (2.5 M) | Cu
The mass of each solid electrode is 2.00 g.
a)
b)
c)
Which of the two is a reducing agent?
Calculate the cell potential when this battery is first connected.
Calculate the cell potential after 10.0 A of current has flowed for 10.0 hours.
(Assume each half-cell contains 1.00 L of solution.)
d)
e)
Calculate the mass of each electrode after 10.0 hourS.
What will cause the battery to die after some time?
