EXPERIMENTAL EVALUATION OF NONISOTHERMAL, FIRST-ORDER REACTION-KINETICS

A procedure for the analyses of nonisothermal, batch reaction data is presented. Nonlinear regression analyses based on a least-squares obje ctive function yield kinetic rate expression parameters from a single experiment. Data collected for the thermal decomposition of benzoyl pe roxide in xylene were analyzed, illustrating differential and integral analyses. The Arrhenius frequency factor and activation energy determ ined were in agreement with published results obtained by isothermal e xperiments. In addition, the regression analyses determined the initia l concentration of the reactant.
