✦ Synopsis

Usmg the blvanate Laplace transform method, the density functions of the residence time dlstnbutlon of the product and reactant, respectively, are determmed m terms of the four roots of the charactenstlc equation and asymptotic relations for the mean and vanance of these dlstnbutlons are given In three special cases, such as the meverslble reactlon, the case when the dlffuslvltles of product and reactant equal as well as when eqmhbnum IS supposed, the charactenstlc roots are exphcltly determmed A new dlmenslonless quantity IS recommended for expenmental parameter estimation
