Determine the equilibrium constant at 255 K for the following reaction under acidic conditions.
4H+ (aq) + MnO₂ (s) + 2Fe²+ (aq) ———› Mn²+ (aq) + 2Fe³+ (aq) + 2H₂O(1)
The two half-reactions are:
MnO₂ (s) + 4H+ (aq) + 2e¯¯ ———› Mn²+ (aq) + 2H₂O(1) E* = 1.23 V
Fe³+ (aq) + e, Fe²+ (aq) E³ = .0.770 V

What is the electron pair geometry?

We know that a compound would have its structure based on the number of electrons pairs that can be found on the valence shell of the atom. According to the valence shell electron pair repulsion theory, the electron pairs that surround the valence shell would be the major determinant of the structure of the compound.

We also have to recall that the number of the lone pairs and the bond pairs in the compound are also a key as we want to determine the structure. This is because, while all the electron pairs count towards the electron pair geometry, the bond pairs count towards the molecular geometry of the compound.
