Which of the following staement (s) `is//are` not true about the following decomposition reaction `2KCIO_(3)rarr2KCI+3O_(2)`A. Potassium is undergoing oxidationB. Cholorine is undergoing oxidationC. Oxygen is reducedD. None of the species are undergoing oxidtion or reduciton

Answer» `2overset(+1)Koverset(+5)Cioverset(-2)O_(3)rarr2overset(+1)Koverset(-1)CI+3overset(0)O_(2)`
(a) O.N of K does not change
(b) Since O.N of CI decreases from +5 to -1 therefore chlorine undergoes reduction and not oxidation
(c )Since O.N of O increases from -2 to O therefore oxygen is undergoing oxidation and not reduction
(d) This statement is also not correct
Thus all the option (a,b,c,d) are not correct
