For a cell given below:
`Ag|Ag^(+)||Cu^(2+)|Cu`
`Ag^(+)+e^(-)toAg,E^(@)=x`
`Cu^(2+)+2e^(-)toCu,,E^(@)=y` ltbr. The value of `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
At LHS (oxidation `2xx(AgtoAg^(+)+e^(-))" "E_(cell)^(@)=-x`
`underline("At RHS" (reduction) Cu^(2+)+2e^(-)toCu" "E_(red)^(@)=+y)`
`underline(2Ag+Cu^(2+)toCu+2Ag^(+)" "E_(red)^(@)=(y-x))`
