Question

For the reduction of silver ions with copper metal, the standard cell potential was found to be + 0.46 V at 2 5 ∘ C . The value of standard Gibbs energy, Δ G ∘ will be ( F = 96500 C mol − 1 ) NEET 2010 (Screening)

TestHub · Accepted Answer

We know that, standard Gibbs energy, Δ G ∘ = − n nF cell ∘ ​ For the cell reaction, 2 Ag + Δ E cell ∘ ​ Δ G ∘ ​ + Cu ⟶ Cu 2 + + 2 Ag = + 0.46 V = − 2 × 96500 × 0.46 = − 88780 J = − 88.7 kJ ≈ − 89.0 kJ ​
