What are homogenous catalyst? Give few examples.
When a catalyst mixes homogeneously with the reactants and forms a single phase, the catalyst is said to be homogeneous and this type of catalysis is called homogeneous catalysis. Some more examples of homogeneous catalysis are: SO2 is oxidized to SO2 in the presence of nitric oxide (NO) as catalyst. Oxidization of CO by O2 in the presence of NO as catalyst. Preparation of diethyl ether from ethyl alcohol using conc. H2SO4 as catalyst Hydrolysis of esters using H2SO4 as catalyst Hydrolysis of sucrose in the presence of dilute sulphuric acid. Mechanism of homogeneous catalysis As pointed out earlier, the catalyst combines with one of the reactant to form some intermediate compound. The intermediate compounds being unstable decompose or combine with each other reacting species to regenerate the catalyst along with the formation of final products. Let us understand the catalytic action of NO in the oxidation of SO2. In this reaction, NO (the catalyst) combines with oxygen to form NO2 (intermediate). The intermediate is consumed in the next step and the catalyst is regenerated.

The two solutions which are having equivalent osmotic pressure are called isotonic solutions. The isotonic solutions at the same temperature also have same molar concentration. If we have solutions having different osmotic pressures then the solution having different

The first method begins with a well defined layer, or boundary, of solution near the center of rotation and tracks the movement of this layer to the outside of the cell as a function of time. Such a method is termed a sedimentary velocity experiment. A
