A Lotus spreadsheet (LS) was utilized as part of a copolymerization study of methyl methacrylate (MMA) with N-phenylmaleimide (MP) and with some derivatives of MP, namely N-o-chlorophenylmaleimide (MOCP), N-p -tolylmaleimide (MPT), and N-o-tolylmalei

In order to obtain the rate constants, k 1 and k 2 , for two competitive, consecutive (series) second-order reactions (CCSR), previous workers have utilized approximate and graphical procedures. However, Frost and Schwemer (FS) were able to derive ex

The present author developed an expression in a previous report that could be applied to the determination of the two rate constants, k 1 and k 2 , for two consecutive irreversible first-order reactions (2CIFR). This expression was solved utilizing v

In our previous publication (Thermochim. Acta 222 (1993) 85), a computer algorithm was devised which allowed the concurrent determination of two rate constants, k1 and k2, for two consecutive irreversible first-order reactions. The Paradox 3.5 databa

Experimental and calculated values are compared in the analysis of two parallel first-order reactions. The method used here to obtain the two rate constants is less tedious and more rapid than the method of Brown and Fletcher.

A mathematical expression was previously derived for the concurrent determination of two rate constants, k 1 and k 2 , for two consecutive irreversible first-order reactions. This expression required the measurement of slopes in order to ascertain th

A relational database manager (DB) was previously employed to estimate values of kinetic parameters from isothermal TG (ITG) and from non-isothermal TG (NITG) data. The Paradox 3 DB, which possesses a powerful application language ( pal ), was utiliz

Spreadsheet analysis (SHTS) of TG (and DTA) data has been employed by the present author to satisfactorily determine kinetic parameters such as activation energy (E) and reaction order (n), as well as mechanism. Many of the functions used in the macr
