Figure 3 shows this variation of m calculated by the linear least square regression of the theoretical results for each a in the range of0<J?5<0.99. As is seen in Fig. 3 , when a<0.l9 m can be approximated by 2/3, as for the ordinary grain model. However, m increases with increase in a and becomes as large as 1.5. When g is about 0.5, m becomes 1, which corresponds to uniform conversion1}. Nomenclature /(r) = density function of a size distribution [-] m = reaction order in solid reactant [-] t
