हिन्दी

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R : \n Assertion A : In equation \( \Delta_r G = -nFE_{\text{cell}} \), value of \( \Delta_r G \) depends on \( n \).\nReasons R : \( E_{\text{cell}} \) is an intensive property and \( \Delta_r G \) is an extensive property.\nIn the light of the above statements, choose the correct answer from the options given below:

  1. A
    Both A and R are true and R is the correct explanation of A.
  2. B
    Both A and R are true and R is NOT the correct explanation of A.
  3. C
    A is true but R is false.
  4. D
    A is false but R is true.

Correct answer · Option A

Both A and R are true and R is the correct explanation of A.

Explanation

\( \Delta_r G \) depends on \( n \) because \( \Delta_r G \) is an extensive property proportional to the number of moles \( n \) transferred, whereas \( E_{\text{cell}} \) is an intensive property independent of \( n \). Hence, R correctly explains A.
