Determine the values of equilibrium constant (K_(c)) and DeltaG^(@) for the reaction Ni(s)+2Ag^(+)(aq)rarrNi^(2+)(aq)+2Ag(s), E^(@)=1.05 V.("Given " 1F=96500"C mol"^(-1))

Answer»

Solution :`DeltaG^(THETA)=-nFE_("cell")^(theta)`
`n=2, E_("cell")^(theta)=1.05V`
`F="96500 C mol"^(-1)`
`DeltaG^(theta)=-2xx1.05xx96500`
`=-202.650kJ`
`DeltaG^(theta)=-RT ln K_(c)`
`lnK_(c)=-(DeltaG^(theta))/(RT)=(-202.650xx10^(3))/(8.314xx298)`
`K_(c)=3.32xx10^(35)`
