Given that `E^(@)(Zn) = -0.76V and E^(@)(Cu) = 0.34V`. Calculate the emf of the cell with cell reaction

A

`-42 V`

B

`1.42 V`

C

`-1.10 V`

D

`+1.10 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`E_("cell")^(0)=underset((Cu))(E_(R)^(0))-underset((Zn))(E_(R)^(0))=0.34-(-0.76)=1.1V`
