NEET · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry

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

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

Answer & Solution

Correct Answer

(B) Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\)

Step-by-step Solution

Detailed explanation

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
