For a cell given below
`Ag|Ag^(+)||Cu^(2+)|Cu`
`Ag^(+)+e^(-)toAg,E^(@)=x`
`Cu^(2+)+2e^(-)toCu,E^(@)=y` then `E_(cell)^(@)` is

A

x+2y

B

2x+y

C

y-x

D

y-2x

Text Solution

Verified by Experts

The correct Answer is:
C
By reduction electrode potential,
`E_(cell)^(@)=E_(R)^(@)-E_(O)^(@)`
`=E_(Cu^(2+)//Cu)^(@)-E_(Ag^(+)//Ag)^(@)=y-x`
