Richard; I expect this to be a surface limited reaction with low viscosity liquids. This is obviously a rate dependent reaction at a syrface. and that is why the elevated temperature. I expect these reactions to be simple for the most part, as most ionic ones are. I do not know if they have found a bacteria that will do this, as they will work faster at higher temps(until they cook!!) The low viscosity will allow for full mixing and the equipment will minimize diffusion in the liquid(it will be fully mixed) there will be no diffusion in the solid as the temp is too low. There may be some limits in crevice penetration as diffusion limits the exchange of material. I think that is why they are going to a finer grind, to get surface exposure forthe reaction. The doubling every ten degrees is not cast in stone, but is a generalisation that does indeed fail in high viscosity/living/organic situations.
