catalysis

Catalysis - It has been mentioned earlier that a catalyst usually increases the rate of reaction. A catalyst is not consumed in the reaction, it is used up in one step and then released in the next step. Catalytic reactions can be classified into two types. They are i) Homogenous reaction..

Catalytic reactions are classified as homogeneous catalysis or heterogeneous catalysis. When a catalyst mixes homogenously with the reactants and forms a single phase it is called a homogenous catalyst. When a catalyst exists in a different phase from that of the reactants it i..

Many reactions in solution are catalyzed by organometallic compounds or transition metal complexes. Example: Wilkinson's catalyst (Ph 3 P) 3 RhCl - Catalyst in hydrogenation of alkene..

Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense catalytic power; they accelerate reactions by factors of at least a m..

Zeolites - Shape-Selective Catalysis by Zeolites - Shape-selective catalysis are those reactions that depend on the pore structure of the catalyst and the size of the reactant and product molecules. In such reactions, zeolites are used as catalysts. Zeolites are microporous alum..
