  Good effort. However, if you evaporate more of your water, then the remainder freezes faster.

  It's not really rate of change... a better statement of this is that there exist some set ups in which a hotter sample of water will freeze faster than a cooler one, because more complex stuff goes on than simply "temperature--". It's not a general rule, and it doesn't rely on any kind of temperature-drop momentum. I know your link doesn't exactly say that it does, but the summary felt kind of misleading.
