The standard cell potential for the electrochemical cell ` Af//Af^+ || AgI//Ag, E_(AfI(s)//Ag)^0 =- 0.151 V`,
` E_(Ag^+//Ag)^@ = 0.799V`.

A

` + 0.950 V`

B

`-0.950 V`

C

` -2 8V`

D

` -1.4 V`

Text Solution

Verified by Experts

The correct Answer is:
B
` Ag|Af^+||Agl|Ag`
`E_("cell") = E_(Af//Ag^+)^@ +E_(1^(-)//Agl(s) Ag)^@`
` =-0.799-0. 151 =- 0.950 V`.
