The reaction, 2MO(s) + CO₂(g) → M₂O₃(s) + CO(g) where M is a metallic element, is spontaneous at high temperatures but non-spontaneous at low temperatures.

If we assume that Δ_rH° and Δ_rS° are constant over a wide temperature range we can deduce that:

Consider the following sketch of the interaction energy for two atoms as a function of distance between the atoms.

Which label, a) to e) points to the region where the attraction between the nuclei and electrons is dominating the interaction?

Represented is what type of bond?

Consider the following sketch of the interaction energy for two atoms as a function of distance between the atoms.

Label e) refers to the point where the interaction energy is lowest and shows how the stable bond length is calculated.  At this point ____________
