Which of the following represents disproportionation of potassium chlorate?

  1. A \(2 \mathrm{KClO}_3 \longrightarrow 2 \mathrm{KCl}+3 \mathrm{O}_2\)
  2. B \(3 \mathrm{KClO}_3 \longrightarrow 2 \mathrm{KClO}_2+\mathrm{KClO}_3\)
  3. C \(4 \mathrm{KClO}_3 \longrightarrow 3 \mathrm{KClO}_4+\mathrm{KCl}\)
  4. D None of the above
Verified Solution

Answer & Solution

Correct Answer

(C) \(4 \mathrm{KClO}_3 \longrightarrow 3 \mathrm{KClO}_4+\mathrm{KCl}\)

Step-by-step Solution

Detailed explanation

\(\stackrel{(+5)}{4 \mathrm{KClO}_3} \longrightarrow 3 \stackrel{(-7)}{\mathrm{KClO}_4}+\stackrel{(-1)}{\mathrm{KCl}}\) Potassium chlorate disproportionate into potassium perchlorate and potassium chloride at higher temperature. Hence, the correct option is (c).
