Which of the following statement is correct ?

MCQ

A
$E_{Cell}$ and $\Delta G$ of cell reaction both are extensive properties
B
$E_{Cell}$ and $\Delta G$ of cell reaction both are intensive properties
✓
$E_{Cell}$ is an intensive property while $\Delta G$ of cell reaction is an extensive property.
D
$E_{Cell}$ is an extensive property while $\Delta G$ of cell reaction is an intensive property.

✓

Answer

Correct option: C.

$E_{Cell}$ is an intensive property while $\Delta G$ of cell reaction is an extensive property.

c
An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system.

An extensive property is a property that changes when the size of the sample changes

$\Delta G =- nF E _{\text {cell }}$

In the above equation the free energy equation is dependent on amount of material of system whereas electrode potential is independent on amount of system.

$E _{\text {cell }}$ is an intensive property and $\Delta G$ is an extensive property
