✦ Synopsis

The problem of the transient mass transfer with first order chemical reaction within a rigid particle is considered. A simple analytical approximation for the solution in the case of negligible external mass transfer resistance is derived. The accuracy of this expression with respect to the exact solution is examined. On its basis a lumped model, in which the effect of the reaction on the mass transfer coefficient during time is taken into account, is develooed. Finally the behaviour of this model in the case of limiting external mass transfer resistance is numerically explored.
