Verified by Experts

(i) Tyndall effect : The phenomenon of scattering of light by colloidal particles as a result of which the path of beam becomes visible is called Tyndall effect.
(ii) Shape-selective catalysis : The catalytic reaction which depend upon the pore structure of the catalyst and the size of the reactant and product molecules is called shape-selective catalysis.
