If \phi denotes reduction potential, then which is true?

  • Option 1)

    E^{\circ}_{cell}= \phi _{right}-\phi _{left}

  • Option 2)

    E^{\circ}_{cell}= \phi _{left}+\phi _{right}

  • Option 3)

    E^{\circ}_{cell}= \phi _{left}-\phi _{right}

  • Option 4)

    E^{\circ}_{cell}=-\left ( \phi _{left}+\phi _{right} \right )

As we learnt in

Electrode Potential -

The potential associated with each electrode is known as electrode potential.

-

 

 If \o is reduction potential, then t^{\circ} all is 

E^{\circ} cell = reduction potential (cathole, right) + Oxidation potential (anode, left)

= Reduction Potential (right) - Reduction potential (left)=\oright\oleft

Correct option is 1.


Option 1)

E^{\circ}_{cell}= \phi _{right}-\phi _{left}

Correct

Option 2)

E^{\circ}_{cell}= \phi _{left}+\phi _{right}

Incorrect

Option 3)

E^{\circ}_{cell}= \phi _{left}-\phi _{right}

Incorrect

Option 4)

E^{\circ}_{cell}=-\left ( \phi _{left}+\phi _{right} \right )

Incorrect
