Question:

(a) In aqueous solution at pH 0, Mn³⁺ disproportionates to MnO₂ and Mn²⁺. Write equations for the two half-reactions involved in this process.

(b) Use Fig. 8.2 to obtain values of Eº for the half-equations in part (a).

(c) Determine Eºcell and a value of ΔGº(298 K) for the disproportionation of Mn³⁺ (aq) at pH 0. Write an equation to which this value of ΔGº(298 K) refers.

Figure 8.2.
