What is homogeneous catalysis ? Give three examples.

Text Solution

Verified by Experts

At catalytic process in which reactant and the catalyst are in the same phase, then the process is called homogeneous catalysis.
Example (1) : Oxidation of sulphur-di-oxide to sulphur trioxide.
`2SO_(2)(g) + O_(2) (g) overset(NO(g))rarr 2SO_(3)(g)`
NO is catalyst.
Example (2) : Acid hydrolysis of methylacetate
`CH_(3)COOCH_(3)(I) + H_(2)O(l) overset(HCl(l))rarr CH_(3)COOH(aq) + CH_(3)OH(aq)`
Example (3) : Acid hydrolysis of canesugar
`C_(12)H_(22)O_(11)(aq) + H_(2)O(l) overset(H^(+))rarr underset("Glucose")(C_(6)H_(12)O_(6)(aq)) + underset("Fructose")(C_(6)H_(12)O_(6)(aq))`
