4. Study of two special cases of consumable interactions
In both cases, we assume that thermal effects within the solid particle are negligible. Under these conditions, the temperature within the solid is equal to T i . If thermal effects do exist, they are limited to the outer diffusion layer.
4.1 Special case of the first family
Material transfer properties and reaction volume are constant, and the operating regime for solid reagent B is purely diffusional. Under these conditions, the composition profile of reagent A in the peripheral zone of thickness is virtually linear, and the flux of reagent A consumed is equal...
