Explain briefly homogeneous catalysis.

Explanation

Homogeneous catalysis: When the reactants and the catalyst are in the same phase (i.e., liquid or gas), the process is said to be homogeneous catalysis. The following are some of the examples of homogeneous catalysis :
Oxidation of sulphur dioxide into sulphur dioxide with dioxygen in the presence of oxides of nitrogen as the catalyst in the lead chamber process.
`2SO_2 (g) + O_2 (g) overset(NO(g))to 2SO_3 (g)`
The reactants, sulphur dioxide and oxygen, and the catalyst, nitric oxide, are all in the same phase
(ii) Hydrolysis of methyl acetate is catalysed by `H^+` ions furnished by hydrochloric acid.
`CH_3 COO CH_3 (l) + H_2 O (l) overset(HCl (l))to CH_3 COOH (aq) + CH_3 OH (aq)`
Both the reactants and the catalyst are in the same phase.
(iii) Hydrolysis of sugar is catalysed by `H^+` ions furnished by sulphuric acid.
`underset("Solution")(C_(12)H_(22) O_(11)(aq)) + H_2 O (l) overset(H_2 SO_4 (l))to underset("Solution")ubrace(underset("Glucose")(C_(6) H_(12)O_6 (aq)) + underset("Fructose")(C_6 H_(12) O_6(aq)))`
Both the reactants and the catalyst are in the same phase.
