The standard cell potential of `Zn|zn_((aq))^(2+)"||"Cu_((aq))^(2+)|Cu` cell is 1.10 V . The maximum work obtained by this cell will be __________.

A

106.15 kJ

B

`– 212.30 kJ`

C

`– 318.45 kJ`

D

`– 424.60 kJ`

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum work obtained `= DeltaG`
` DeltaG= -nFE^(@)`
`Zn +Cu^(2+) rarr Cu+ Zn^(2+)`
n = 2 electrons
` DeltaG -2xx 96500 xx1.1 J`
`= -212.3kJ`
