_____________theory explains why the catalyst remains unchanged in mass and chemical composition at the end of the reaction and is very effective even in small quantities.

_____________is a type of colloid in which the dispersed phase and dispersion medium are solids.

_____________is the process of separating the colloidal particles from the solvent and suitable solutes present in the colloidal solution by specially prepared filters,which are permeable to all substances except the colloidal particles.
