USE OF DATABASES IN THERMAL-ANALYSIS .5.

A mathematical expression was previously derived for the concurrent de termination of two rate constants, k1 and k2, for two consecutive irre versible first-order reactions. This expression required the measureme nt of slopes in order to ascertain the required reaction rates. In thi s paper, a relational database manager (DB) was employed to estimate v alues of the two rate constants using this expression. For this purpos e, a computer algorithm was developed using the Paradox 3 DB which pos sesses a powerful script language (PAL). Database analyses were carrie d out using both theoretical and experimental data. The PAL script emp loyed is described and the resulting k1 and k2 values are compared wit h the assumed and reported values.
