Answer to Question #201140 in General Chemistry for Mark

Question

Determine if the decomposition of potassium chlorate (KClO₃) is spontaneous or not

2KClO₃ (s) —› 2KCl(s) + 3O₂ (g)

Answer 1

When potassium chlorate KClO3 is being heated then it heals Potassium ChlorideKCl and oxygenO2.

However this method is being used for the manufacturing of Oxygen gas and you can very well manipulate the rate of reaction by adding a catalyst to it which is generally Mn O2.
