JEE Mains · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry

an oxidation-reduction reaction in which \(3\) electrons are transferred has a \(\Delta G ^{\circ}\) of \(17.37\, kJ\) \(mol ^{-1}\) at \(25^{\circ} C\). The value of \(E _{\text {cell }}^{\circ}\) (in \(V\) ) is........ \(\times 10^{-2}\) \(\left(1 F =96,500\, C\, mol ^{-1}\right)\)

  1. A \(6\)
  2. B \(8\)
  3. C \(10\)
  4. D \(12\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(6\)

Step-by-step Solution

Detailed explanation

\(\Delta G ^{\circ}=- AFE ^{\circ}=-3 \times 96500 \times E ^{\circ}\) \(\Rightarrow E ^{\circ}=-6 \times 10^{-2} V\)
