Title: Anomalous Equilibrium Reaction, any real instance of it?
Post by: Twigg on March 31, 2011, 08:37:59 PM

Suppose a hypothetical reaction:

10²⁶ X(aq)  :rarrow: X_10²⁶(s)

I imagine it would be pointless to assign a Keq because the concentrations would not really approach any limit because of the massive order of magnitude of the displacement.

Is there any instance of such an anomaly, probably on a lower order of magnitude?

probably the only equilibria of the sort I could think of is sulfur (S₈, S₆, S₂ and more less common ones)

I thought about that one too. Maybe the hydration of starch? My only problem with that is that it's not an elementary reaction.
How about this one? I'm not sure it's elementary, and I highly doubt it's real, but here it is:

[Mn(NH₃)₆]₃[Fe(CN)₆]₇(l) + 4H₂O(l) -> Fe(MnO₄)₃(l) + 6Fe(CN)₃(l) + 18 NH₃(g) + 8 HCN(g) + 13CN^-(l)

Man that took a while to write.
