Find the equilibrium constant for the reaction `:`
`Cu^(2+)+In^(2+)hArrCu^(o+)+In^(3+)`
Given that `E^(c-).._(Cu^(2+)|Cu^(o+))=0.15V,E^(c-)._(ln^(2+)|ln^(o+))=-0.4V,`
`E^(c-)._(ln^(3+)|ln^(o+))=-0.42V`

Text Solution

Verified by Experts

The correct Answer is:
`K_(C)=10^(10)`
`ln^(+)toln^(3+)+2e^(-)" "0.42"volt"`
`underline(ln^(2+)+etoln^(+))" "-0.4"volt"`
`underline(ln^(2+)toln^(3+)+e^(-))`
`E^(@)=0.44"volt"`
`E_(cell)^(@)=0.15+0.44=0.59"volt"`
`0=0.59-(0.059)/(2)logK.`
`K=10^(10)`
