Define the following terms :
(i) Shape-selective catalysis
(ii) Kraft temperature
(iii) Peptization
i) Shape-selective catalysis are the catalytic reaction that depends upon the pore structure of the catalyst and the size of the reactant and product molecules.
ii) The formation of micelles takes place only above a particular temperature is called Kraft temperature (Tk)
iii) Process of converting a precipitate into colloidal sol by shaking it with dispersion medium in the presence of a small amount of electrolyte is known as Peptization.
