MCQ
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R:
Assertion (A): In equation $\Delta_{ r } G =- nFE E_{\text {cell }}$, value of $\Delta_{ r } G$ depends on $n$.
Reason (R): Both $E _{\text {cell }}$ and $\Delta_{ r } G$ are extensive properties.
In the light of the above statements, choose the correct answer from the options given below:
  • A
    A is false but R is true.
  • B
    Both A and R are true and R is the correct explanation of A
  • C
    Both A and R are true but R is NOT the correct explanation of A
  • A is true but R is false

Answer

Correct option: D.
A is true but R is false
(D)
Free energy is extensive property, and $E _{ Cell }^{\circ}$ is an intensive property $\Delta_{ r } G$ is depends on the ' $n$ ' which is number of electron transferred in the reaction
$\Delta_{r} G=-nFE{ }^{\circ}$
