Give reasons for Cation vacancies in some crystals make them good catalysts.


The catalytic activity dependsvery much on the surface area per unit mass of the sample.
Transition metal corresponds show metal deficiency due to absence of metal ion from its lattice. The charge is balanced by an adjacent ion having higher positive charge which ultimately increases chemisorption.
