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

Answer»

`x+2y`
`2x+y`
`y-x`
`y-2x`

Solution :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))`
