433. Delta H Versus K-1
by Russell S. Drago, Department of Chemistry, University of Illinois, Urbana, Illinois 61801 This program can be used to determine best-fit values for H and K for a reaction between an acid and a base. It has been written for those cases in which a 1:1 adduct is formed, although it may be used for a system which forms a 2:1 adduct to analyze a region for which no 2:1 adduct has yet formed. The program is able to analyze calorimetric data by the incremental and the cumulative methods and can analyze spectroscopic data by the cumulative method. To perform an incremental fit, NFIT must be zero. Since the incremental evolution of heat (H) is a function not only of the total acid and base concentrations but also of the previous injection, the data cards must be in the same order as that in which the experiment was done. To simultaneously analyze multiple sets of data, i.e., to obtain one H and one K, KDATA should equal 1 for the first injection of each additional set. For cumulative fits, NFIT>0, and the order of data cards and the value of KDATA are irrelevant. FORTRAN IV (IBM) Lines of Code: 275 |
