Which of the following represents disproportionation of potassium chlorate?

Options

  1. A(2 KClO ₃ 2 KCl +3 O ₂ )
  2. B(3 KClO ₃ 2 KClO ₂+ KClO ₃ )
  3. C(4 KClO ₃ 3 KClO ₄+ KCl )
  4. DNone of the above

Correct answer

C. (4 KClO ₃ 3 KClO ₄+ KCl )

Step-by-step solution

( (+5) 4 KClO ₃ 3 (-7) KClO ₄ + (-1) KCl ) Potassium chlorate disproportionate into potassium perchlorate and potassium chloride at higher temperature. Hence, the correct option is (c).
