Mg + cu² ==> Mg² + cu


E°cell = 2.71v , 1F = 96500​

Answer 1

✩ Correct Question :

• calculate ∆rG° for reaction

• Mg + cu² ==> Mg² + cu

• E°cell = 2.71v , 1F = 96500

✩ Required Solution :

• Using formula ∆g = -NFE°cell

✩ value given to us :-

• N = -2

• F = 96500

• E ° cell = 2.71 v

✩ Putting value in formula :-

• ∆g = -2 × 96500 × 2.71

• ∆g = -193000 × 2.71

• ∆g = 523.03 kgmol-1
