For the following cell
`Zn(s)|ZnSO_4 (aq) ||CuSO_4 (aq)|Cu(s)`
When `[Zn^(2+)]` is ten times of `[Cu^(2+)]` the expression `Delta G ` ( in `J mol^-1`) is

A

2.303 RT +1.1F

B

1.1F

C

2.303RT -2.2F

D

2.2F

Text Solution

Verified by Experts

C
`Delta G=Delta G^@+2.303RT log""([Zn^(2+)])/([Cu^(2+)])`
and `Delta G^@=-nFE^@=2 times 1.1F` find `Delta G (E_(cell)^@=1.1V)]`
