MCQ
Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$

Assertion $A:$ In equation $\Delta_r G =- nFE _{\text {cell }}$ value of $\Delta_r G$ depends on $n$.

Reasons $R$ : $E_{\text {cell }}$ is an intensive property and $\Delta_{ r } G$ is an extensive property.

In the light of the above statements, choose the correct answer from the options given below

  • A
    $A$ is false but $R$ is true
  • Both $A$ and $R$ are true and $R$ is the correct explanation of $A$
  • C
    Both $A$ and $R$ are true and $R$ is NOT the correct explanation of $A$
  • D
    $A$ is true but $R$ is false

Answer

Correct option: B.
Both $A$ and $R$ are true and $R$ is the correct explanation of $A$
b
The value of $\Delta_r G$ depends on $n$ value as per the equation $\Delta_r G=-n F E_{\text {cell }}$ Where $E$ is the emf of the cell and $nF$ is the amount of charge passed.

So, assertion statement is correct

Ecell is an intensive property while $\Delta_r G$ is an extensive thermodynamic property

So, reason is correct but not explaining the assertion
