The standarde.m.f. of a cell involving one electron charge is found to be 0.591V at 25^(@)C the equilibrium constant of the reaction is (F=96500C "mol"^(-1):R=8.314 JK^(-1)"mol"^(-1))

Answer»

`1.0xx10^(1)`
`1.0xx10^(30)`
`1.0xx10^(10)`
`1.0xx10^(5)`

SOLUTION :At 298
`E^(@)=(0.0591)/(N)"log" k_(c)`
`0.591=(0.0591)/(1)"log"K_(c)`
`"log" k_(c)=(0.5910)/(0.0591)`
` "log"k_(c)=10`
`K_(c)=10^(10)`
