Consider the half-cell reduction reaction: aligned & Mn ²⁺+2 e⁻ Mn , E ^ o =-1.18 ~V & Mn ²⁺ Mn ³⁺+e⁻, E ^ o =1.51 ~V aligned The E ^ for the reaction 3 Mn ²⁺ Mn ^0+2 Mn ³⁺ , and possibility of the forward reaction are respectively

Question

Quantrex Academy · Accepted Answer

Correct answer: D. -2.69 ~V and no

Mn ²⁺ 2 e⁻ Mn E ^0=-1.18 ~V aligned & 2 Mn ²⁺ 2 Mn ³⁺+2 e E ^ =-1.15 ~V & 3 Mn ²⁺ Mn +2 Mn ³⁺ E ^ =-2.69 ~V aligned The process is non spontaneous because the E ^ value is negative.
