✦ Synopsis
An analytical solution is developed for the problem of transient diffusion and first order reaction in a solid flanked by two well mixed fluid compartments. This solution is necessary and useful in describing unsteady-state measurements in a Wicke-Kallenbach diffusion cell or reaction studies in a single pellet reactor. It is shown that a proper choice of an inner product vector space., following the methodology developed by Ramkrishna and Amundson[l4,15], leads readily to the desired solution and guarantees its completeness, This solution is valid for the equivalent heat transfer problem also.

A systematic and straightforward approach to obtain accurate transient responses of circular arches subjected to point loading and support motions is presented. The Laplace transform is applied to the time variable. Then, an analytical solution is formulated in the s-domain. Finally, an efficient an
## Abstract In a diffusion cell experiment, the presence of a film diffusion resistance, in series with intrapellet diffusion, leads to loss of precision in the estimation of intrapellet diffusivities. A general strategy, extendable to other problems, for quantifying a parametric region where film
