`E_(1) and E_(2)` are two half-cells of electrode potential which when combined form a cell of electrode `E_(3),` then which of the following is true (where `n_(1) , n_(2)` and nu are number of electrons exchanged in first, second and combined half cells)?

A

`E _(3) = E _(2) - E _(1)`

B

`E _(1) = ( E _(1) n _(1) + E _(2) n _(2))/( n_(3))`

C

`E _(3) = ( E _(1) n _(1) - E _(2) n _(2))/( n _(3) ^(2))`

D

`E _(3) = E _(1) + E _(2)`

Calculating the Gibbs Energy change from electrode Potentials: Using standard electrode potentials, clacu-late the standard Gibbs energy change at 25^(@)C for the following cell reaction. Strategy: To calculate DeltaG_("cell")^(@) , we use the equation DeltaG_("cell")^(@) = -nFE_("cell")^(@) , where E_("cell")^(@) is obtained by using a table of standard potentails and n can be inferred from the balanced chemical equation. The cell reaction equals the sum of the half-cell reactions after they have been multiplied by factors so that the electrons cancel in the summation. Note that n is the number of electrons involved in each half-reaction.

The standard electrode potentials at 298 K are given below: E_(Zn^(2+)| Zn )^(0) = -0.76 volt and , E_(Fe^(2+)|Fe)^(0) = -0.44 volt , E_(H^(2+)|H_(2))^(0) = -0.0volt Which of the two electrodes should be combined to form a cell having highest EMF? Identify the cathode and the anode and write the cell reaction. Also mention the direction of flow of electrons in the external as well as the internal circuit.
