Quantrex Academy · Accepted Answer

Correct answer: D. X₁+X₃+2 X₂

Cu ⁺²+ e ⁻ Cu ⁺ ; E ^ = X ₁ ~V G ₁^ =- FX ₁ ....(i) In ⁺³+2 e ⁻ In ⁺¹ E ^ = X ₂ ~V G ₂^ =-2 FX X ₂ ....(ii) In ⁺²+ e ⁻ In ⁺ E ^ = X ₃ ~V G ₃^ =- FX ₃ ....(iii) aligned & From Eqn. (i) + (iii) - (ii) & In ⁺²+ Cu ²⁺ ⁺³+ Cu ⁺ G ^ =- FE ^ & G ^ =- F ( X ₁+ X ₃-2 X ₂ )=- FE ^ & E ^ = ( X ₁+ X ₃-2 X ₂ ) aligned
