During manufacture of chlorine from brine -

`DeltaG^(@)` of the overall reaction is `-ve`

`DeltaG^(@)` of the overall reaction is `+ve`

the value of `DeltaE^(@)` of the overall reaction is `-ve`

the value of `DeltaE^(@)` of the overall reaction is `+ve`

`Cl^(-)(aq)rarr(1)/(2)Cl_(2)(g)+e, E_("cell")^(@)=+1.36V`

`2H_(2)O(l)rarrO_(2)(g)+4H^(+)+4e, E_("cell")^(@)=+1.23V`

`Na^(+)(aq)+e rarr Na(s), E_("cell")^(@)=-2.71V`

`H^(+)(aq)+erarr(1)/(2)H_(2)(g),E_("cell")^(@)=0.00V`

(A) Reduction

(B) Hydrogenation

(D) Oxidation.
