Question

In the reaction, \[\ce{H2O2_{(aq)} ->[I^-_{( aq)}] H2O_{(l)} + \frac{1}{2} O2_{(g)}}\] iodide ion acts as ____________.

Options

• homogenous catalyst

• acid catalyst

• heterogenous catalyst

• enzyme catalyst

Answer 1

In the reaction,  \[\ce{H2O2_{(aq)} ->[I^-_{( aq)}] H2O_{(l)} + \frac{1}{2} O2_{(g)}}\] iodide ion acts as homogenous catalyst.

Explanation:

For the reaction,

 \[\ce{H2O2_{(aq)} ->[I^-_{( aq)}] H2O_{(l)} + \frac{1}{2} O2_{(g)}}\]

Iodide ion acts a homogenous catalyst as the phase of I⁻ and reactant, H₂O₂ is aqueous (same).
