What is the standard cell potential E^(@...

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`

A

`1.2V`

B

`0.53V`

C

`0.26 V`

D

`-0.53V`

Text Solution

Verified by Experts

The correct Answer is:
C

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