Given below are the half-cell reactions: Mn²⁺ + 2e⁻ → Mn; E^(o) = -1.18 V 2(Mn³⁺ + e⁻ → Mn²⁺); E^(o) = +1.51 V The E^(o) for 3Mn²⁺ → Mn + 2Mn³⁺ will be:

(C) – 2.69 V; the reaction will not occur

(A) – 0.33 V; the reaction will not occur

(B) – 0.33 V; the reaction will occur

(D) – 2.69 V; the reaction will occur
