Answer:
The ratios of mole O2 to mole KClO3 are: 3/2, 1.5/1,1/2
Explanation:
The 3 possible equation of reaction for the decomposition of KClO3 are:
2KClO3 ==> 2KCl + 3O2
KClO3 ==> KCl + 1.5O2
2KClO3 ==> 2KClO2 + O2
When potassium chlorate (KClO3) is heated in the presence of manganese dioxide catalyst, it decomposes to form potassium chloride and oxygen gas.
