Which of the following statements are not true about the following decomposition reaction?2KClO3⟶2KCl+3O2

2K+1 Cl+5 O3-2⟶2K+1Cl-1 + 3O20(a) The oxidation number of K does not change, thus K undergoes neither reduction nor oxidation. Thus, option (a) is not correct.(b) The oxidation number of chlorine decreases from +5 in KClO3to -1 in KCl, Hence Cl undergoes reduction. (c) Since, oxidation number of oxygen increases from -2 in KClO3 to 0 in O2, so oxygen is oxidized. (d) This statement is not correct because Cl is undergoing reduction and O is undergoing oxidation.
