Question

Whick of the following statements is true.

Reduction of hydrogen peroxide has slow reaction kinetics.

Oxidation of I- has slow reaction kinetics.

Oxidation of glucose has slow reaction kinetics.

Reduction of Cu2+ has slow reaction kinetics.

Reduction at ion selective electrodes has slow reaction kinetics. Please give explanation

Answer 1

In given question, the points given are doubtful without presence of oxidising or reducing agent how will determine kinetics.

Generally hydrogen peroxide is unstable and slowly decompose in the presece of light

Reduction of hydrogen peroxide is a slow reaction we can determine rate of reaction in the lab, by use of potassium iodide in acidic condition.

oxidation of iodide is a slow reaction kinetics and can be determine with help of hydrogen peroxide.

Oxidation of glucose also slow reaction kinetics can be determine in the lab.

Reduction of Cu2+ is also slow rrreactionkinetics

But reduction at ion selective electrode is the fast reaction kinetics.
