β¦ Synopsis
A procedure has been suggested for analytical prediction of conversion-time behaviour of gas-solid non-catalytic reactions which are first order with respect to the gaseous reactant but of any general form with respect to the solid species. Based on this method analytical solutions have been presented for some of the commonly encountered rate forms including the grain model. These solutions predict the behaviour of the system extremely well upto about 50-70% conversion of the solid.

Previous models of noncatalytic gas-solid reactions are based primarily on parallelpore representations, thus excluding important topological effects of the porous medium. This paper utilizes network representations and percolation theory to develop expressions for pore closure time and the evolutio
## Abstract Analysis of singleβpore behavior in a porous pellet of reactant is used to develop a new model for predicting the conversionβtime relationship for gasβsolid noncatalytic reactions. The model accounts for the influence of pore diffusion, diffusion through the product layer which builds u
