Question
Define homogeneous catalysis and give any two examples.
✓
Answer
When the reactants and the catalyst are in the same phase, it is said to be homogeneous catalysis.
e.g.
$i.$ Iodide ion $(I^–)$ is used as homogeneous catalyst in decomposition of aqueous hydrogen peroxide because both $I^–$ and $H_2O_2$ are present in the same aqueous phase.
$ii.$ Hydrolysis of sugar is catalysed by $H^+$ ions furnished by sulphuric acid.
All reactants and catalyst are in same solution phase.
