Unreasonable Arrhenius plots

[enochd]

In many cases, the Arrhenius plots have limits that entirely negate their purpose. For instance, reactions with relevance only above a certain T do not need to be plotted down to 298. This can result in so many orders of magnitude in rate displayed that it's difficult to make sense of what is displayed. It would be nice we use designate T limits within the input forms for training rates.
