After completing this chapter, you will be able to:
Show how mass transfer affects the rate at which a gas reacts with a solid.
Calculate the rate of reaction in a relatively non-porous solid based on the so-called shrinking core model.
Calculate the rate of reaction of a porous solid on the basis of a diffusion-reaction model.
Derive expressions for the conversion of the solid as a function of time.
Characterize the structural changes of the solid due to a reaction and see how it affects transport properties and the rate of conversion of the solid.
Examine the effects of structural changes such as pore plugging/ opening and in some cases, an incomplete conversion of the solid reactant.
