Monomolecular cracking and dehydrogenation of n-butane are characterized for 10-MR zeolites that differ in cavity size. Terminal cracking and dehydrogenation rates are enhanced by higher transition state entropies at cavities and channel intersections, while such structural features, when large enough, appear to be detrimental to the rate of central cracking.
