Answer» SOLUTION :CATALYSIS is of two types : (i) Homogeneous catalysis : A CATALYTIC reaction in which the reacting SUBSTANCE and the catalyst are in the same phase is called homogeneous catalysis. For example: `CH_3COOH_3(l) + H_2O (l) overset(HCl)to CH_3COOH (l) + CH_3OH(l)` (ii) Heterogeneous catalysis: A catalytic reaction in which the reacting substance and the catalyst are in different phases is called heterogeneous catalysis. These catalysts are usually SOLIDS. This type of catalysis is also called surface catalysis. For example: `2SO_2 (g) + O_2(g) overset(V_2O_5)to 2SO_3(g)` |
