179. ACTEN: Arrhenius Activation Energies and
Frequency Factors
by Robert W. Crossley and Ernest A. Dorko, Air Force

Base, Dayton, Ohio 45433
This program evaluates and displays sums of squares of
the Arrhenius equation in both exponential and
logarithmic forms over selected ranges of the Arrhenius
parameters. The program iteratively constricts the
search ranges to minimize the sums of squares. The
program is capable of handling ill-conditioned sum-of-
squares surfaces, and these surfaces can be examined in
any level of detail desired.
The earlier version of this program could handle only
the Arrhenius expression for rate constants. The new
version can handle concentration dependencies as well
as the positive form of the exponential term.
