Later corrections to this equation include Trautz and Lewis' collision theory, as well as Wigner and Eyring's transition state theory.  It was first proposed by van't Hoff in 1884, and later was justified by its namesake.  When expressed in terms of molecular units, the Boltzmann constant is used instead of the universal gas constant.  The modified version of this equation makes explicit the temperature dependence of its pre-exponential factor, which accounts for a reaction's rate coefficient.  FTP, identify this equation named after a Swedish scientist that calculates
