✦ Synopsis
For a certain simple class of chemical reaction networks, viz. rank E = 1, the introduction of an effective scalar diffusion coefficient allows the vector integro-differential equation describing the performance of a multicomponent batch heterogeneous chemical reaction system to be reduced to the scalar integro-differential equation solved earlier in a study of isomerization networks. In particular if the reaction 1 $ 2 takes place in an inert solvent then in the limit of infinite dilution the effective scalar diffusion coefficient reduces to l/v9 -X,. /vD,, +X,* /dD,,. We translate into the framework of our model the experimental studies of slurry reaction systems thought to be chemically controlled, e.g., the studies of Satterfield et al. and Kb;lbel and Maennig. We estimate the degree of chemical disguise, finding it to be important in the intermediate to high temperature range of the latter.
