Question

Which of the following regarding Standard Electrode Potential is correct?

• A. It is an extensive property.
• B. It changes on multiplying or dividing the cell reaction by any constant.
• C. It does not change on multiplying or dividing the cell reaction by any constant.
• D. Both (a) and (b)

Answer 1

The correct option is C It does not change on multiplying or dividing the cell reaction by any constant.

Standard Electrode Potential:

1. It is an intensive property and hence mass independent.
2. It does not change on multiplying or dividing the cell reaction by any constant.

$\Delta G^{\circ }=-nF{E}_{cell}^{\circ }$
where,
$\Delta G^{\circ }=\text{Change in Standard Gibbs' free energy}n=\text{no. of moles of electron transferred in a reaction}F=\text{Faraday constant}{E}_{cell}^{\circ }=\text{Standard Electrode potential}$
