Since the argument becomes too small when using frac, is there an alternative way to reduce the size of the exp argument?

    it is very rare to need dfrac rather than frac and certainly not in an exponent

You asked,




is there an alternative way to reduce the size of the exp argument?




If one uses exp notation, one should not raise the argument to superscript height. Instead, simply encase the argument in round parentheses, square brackets, or whatever fence symbols are most suitable to the task.



Separately, to avoid having to display fractional expression in superscript position, do consider using so-called inline-fraction notation. E.g., instead of writing e^fracuv, write e^u/v -- or exp(u/v).

    First, don't use $$ .. $$ for displayed math, use [ .. ] instead. Second, you can make the fraction in the exponent larder than frac in two ways; either expand -E_a/RT or use normal size of frac by any of several methods, I here used mbox. tfrac will also do the same but is easier.

      As Mico explain it, please avoid using a exponent argument with the function exp. Either use exponent with the number e, or use parentheses with the function exp.
