## Homework Statement

Consider the reaction that produces $$[MCl_{6}]^{3 - }$$ thus:
$$[M(H_{2}O)_{6}]^{2 + } + 6 Cl^{ - } \leftrightarrow [M(Cl)_{6}]^{2 + } + 6H_{2}O$$
where $$M = Cr, Mn \text{ or } Fe$$. Ascertain the stability of complexes.
:)
Also, determine the order of $$K_{eq}$$ values when the reaction is carried out with these three metals.

## Homework Equations

I guess we can use the fact that $$\Delta_{o} = \frac{hc}{\lambda}$$
