What is the standard cell potential E^(@) for an electrochemical cell in which the following reaction takes place spontaneously ? Cl_(1) (g)+ 2Br ^(-) to Br_(2) (aq) +2Cl^(-) , Delta G^(@)=-50.6kJ

Answer»

`1.2V`
`0.53V`
`0.26 V`
`-0.53V`

SOLUTION :`DeltaG^(@)=-nFE^(@) . E^(@) =(-DeltaG^(@))/(NF).`
`E^(@) =(-(-50.61J))/(2xx96500xx10^(-3))=0.26V`
