In the electrolysis of aq. NaCl solution which half-cell reaction will occurs at anode

A

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

B

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

C

`H^(+) + e^(-) rarr (1)/(2) H_(2) ,E_("cell")^(@)= 0.00V`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
In the electrolysis of aqueous sodium chloride solution, chlorine gas is liberated at the anode. This is because `Cl^(-)` ions have lower discharge potential than `OH^(-)` ions.

Fuel cells convert the energy produced during the combustion of fuels cells directly into electrical energy. Probably the most successful fuel cell so far is hydrogen oxygen fuel cell, which has ben used in spacecraft. The electrodes consist of porous screens of titanium coated with a layer of platinum catalyst. concentrated KOH or NaOH soloution is placed beween the electrodes to serve the as electrolyte. hydrogen and oxygen gases are bubbled through the porous electrodes into the electrolyte solution The following electrodes reactions occur: At anode: 2H_2(g)+4OH^(-)(aq)rarr4H_2O(l)+4bare At cathode: O_2(g)+2H_2O(l)+4barerarr4Oh^-(aq) Overall reaction: 2H_2(g)+O_2(g)rarr2H_2O(l) In this cell, the gaseous materials are consumed and continously supplied. The thermodynamic properties of fuel cell reaction at 25^@C are: DeltaH^@=-285.8kJ mol^-1,DeltaG^@=-237.2kJ mol^-1, E^@=1.23V If the potential of the half cell reaction is at cathode is, E^@=0.41V , then E^@ for the half cell reaction at anode is
