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 average translational kinetic energies and speeds of the molecules of a gas can be calculated.The result that the kinetic energy of 1 mol of the molecules of a gas is equal to 3/2 RT can be used to obtain numerical values for the
